Keep iterating over this (M1 -> M2 -> M1 -> M2) until the beam goes through both points at the same time. If you want to make a really big glass bead reflector, see Sean Michael Ragan’s projection screen project. Using two mirrors enables you to alter the direction as well as parallel shift the laser beam, making it easier to align the beam expander and Pockels cell. Established 2008, Laser Mirror Alignment Tutorial for Vertical Laser XL. The tasks involved with aligning the Vertical Laser XL involve aligning three mirrors. Remember not to unscrew so far as to where the screw comes completely out. The support keeps the mirror in the proper position. What we want to know is where the laser is hitting the first mirror. 4' x 8' Vertical Laser XL - Laser Cutter/Engraver, 40W CO2 Laser Cutter and Engraver (blackTooth). In the video you can see where the two mirrors are aligned toward the bottom of the gantry and then reflect up to the mirror that is on the nozzle which is stationed on the gantry. We need to adjust the mount to align the mirror. Always use appropriate safety gear and have a fire extinguisher nearby no matter what laser machine you are using. Once we were all set up, we ran a test to make sure the nozzle would run in a box confined to the material. This method suitable for all HL laser machine equiped with Reci W2,W4, and W6, W8 CO2 laser tube. CAUTION: Take great care when using masking tape. The other two mirrors will be static and not move in relation to the laser … Masking tape can ignite and burn very easily. It is recommended that you keep doing this process at the bottom, middle, and top of the gantry position so you know you have perfect alignment in a straight line. This configuration is specifically useful for aligning multiple laser beams on the same target. When you pulse the laser, be ready to take action to extinguish a flame if one does form. If the beam is not aligned, it will not go through the Pockels cell. Please contact our Customer Service Department for any urgent needs. The x axis movement of the objective lens has to be parallel to the laser beam #1 mirrors has to be at -45 degrees to the lasers beam. Take off the large lens cap on the front of the telescope. Next we needed to make sure it was still centered on the bottom and middle levels as well. Always use gloves when handling mirrors and lenses. 3/32 Hex (Allen) Wrench 3. Align the 3rd mirror to your lens not the Z axis of travel. Now before we fire the laser, we will remove the mirror for safety, as the laser could bounce off the mirror and pose a safety threat. Since the tube is riding on the gantry, you only have to align the laser on one main axis. Si-mirrors and ZnSe lens has a coating you dont want on your fingers, aswell as your fingers contain oils you don´t want on your lens/mirror. Tax Certificates. Or you can use a movable target to give you two points of reference. June 29, 2020 / by k40sam / in K40 Laser Cutter If you have just bought a new K40 laser cutter or have replaced your mirrors, chances are that you are going to need to align your mirrors Although this demonstration is using a 50W ebay Chinese laser cutter, the principles are the same if you are using the K40 laser cutter. Pulse the laser and burn a hole. You may have to adjust the angles of the mirror slightly. Before we test, we need to make sure the motors and controller are turned on. Now we’ll see if the beam can pass through any part of this. Proceed at your own risk. Now we will continue with putting back the mirror holder and fastening it back onto the mirror mount. After tweaking the alignment in multiple positions, we found we had perfect alignment on all three points, so we put the assembly back together. The next thing we need to do is make sure the mirror is going to hit the lens at the center of its’ opening. If moving the target to a farther position causes it to become misaligned, use the second mirror to achieve realignment. Once we’ve done this we fire the laser again to see what happens. Therefore I would like to explain how it is done easily and as accurate as possible. Service Alert: Same day shipping service from Edmund Optics USA will be impacted today, February 1, due to inclement weather and carrier delays. Since the placement of the target dictates the path of the beam, a target should strategically be placed near the exit of the mirror with the other point of reference farther away. When you’re adjusting the lens position, first you can see the mounting hole and how it is mounted on the machine. Optical Improvements. After another test we found that it was too far to the left, so we went too far on the adjustment. Let’s now talk about how to move the frame out. For PERFECT lens head and mirror alignment. Remember again: These tasks can potentially be dangerous. Make sure it cannot pass through and damage anything. The middle finger on the holder should push the button on the cat laser. You can see the Z shaped pattern the beam makes in the Z-fold configuration. Use a fresh piece of tape to secure the target tape pad. Also note the direction of the plane and convex surfaces of the lenses to minimize the angles at the optical surfaces. By adjusting the orientation of the second mirror the angle of … Run your finger on the masking tape around the edge of the circle so you can tell where it is. This position is furthest from the laser tube so any movements will be amplified across the distance. If you don’t have a Scientifica LED alignment tool, the same principle can be achieved using a sample with a crosshair along with a bright visible transmitted … Now we’re ready to align the lens at different levels. You can also put an o-ring to get a better hold between the nut and mirror. We’re going to take the assembly off and using tape once more. Thanks for watching. Use mirror 1 to align for the close point and mirror 2 to align for the far point. Remember to check out EO's other laser optics and products on our website. When you’re taking the mirror out, it will not affect the angle. Ensure that your input laser beam is at a constant height above your table and align mirror 2 (which should be in the middle of the translation stage) so that the reflected beam is nearly coming back to the input of the laser and is in line with the axis of the stage. The laser needs to be able to hit the center directly. Be sure to again install something to absorb any laser energy. Remember, always wear eye protection when dealing with lasers. Align the 3rd and most critical mirror first. There is two types of cleaning i suggest on heavy use, you can see yourself after a days work how filthy the mirrors get and adjust the cleaning needed. Machine Type:Mini 18 and 24 and Helix Laser Tools Required: 1. The always on red laser makes mirror 3 alignment … When testing alignment the best medium i have found is regular painters tape (masking tape). There are two large screws on the mount that are very apparent, but there are also smaller screws. Use a q-tip and some alcohol to clean the mirrors. 394 A Appendix: Practical Guide to Optical Alignment f 1 f 2 From laser Widened filtered beam Figure A.1 A telescope with a pinhole in the focus for cleaning up the laser beam and making it a spatially extended parallel wave. The high test yielded a bit of a high result, so we adjust the mount slightly to bring it down a little bit. Laser Head assembly and Front and Rear Mirror assemb lies. Check for a small dot in the centre of the primary mirror. We want it to hit as close to the center as possible. If you would like more information or have questions, feel free to contact our Technical Support or click the following link. You must align it with the collimation cap’s reflection in the secondary mirror. One mirror will be reflecting the laser energy from the laser tube. If the tube from end to end is not aligned (meaning the back of the laser tube is also viewable in the mirrors, which cannot be seen) then the beam will not hit the expected target. 12. If you decide to follow these instructions, please do so at your own risk. Disclaimer: These tasks are potentially dangerous and proper caution should be exercised. Apply some alcohol to the mirror and gently rub it onto the mirror lens to remove any residue or debris. We’re going to put the mirror mount back into place and put a piece of masking tape over the circle as we did before. Only punch the button for a millisecond. Finally, the Spatial Filter assemblies and apertures will be installed and the laser aligned for 1064nm Q-Switched TEMOO operation. The two most common set-ups for alignment are the Z-fold and the Figure 4 configurations. If it is to the left or the right, you will need to adjust the mirror accordingly. The silver side is the back of the mirror. Any distance is fine, but the farther away the target is, the more precise the alignment will be. A primed and inspected fire extinguisher should always be near laser equipment. Insert the correct way and then put the set screw back. – Adjust mirror 1 until you hit center on mirror 2 in bottom left position. Fold a piece of tape a few times to make padded square, place this square over the target mirror. You can use these techniques with traditional laser cutters in which the tube is stationary, but remember you will have to do this on two axes and when you get to the final axis, make sure that the first mirror (that reflects the initial energy) is very well aligned so that there will be minimal diversion when aligning the final mirror on the nozzle. Retroreflectors are ideal for aligning laser intrusion alarms and communication systems. We’re first going to move the nozzle down toward the mirror. The parts we will be working on specifically on the Vertical Laser XL will be where the tube aligns with the mirror. Go around the edge with your finger again to get an idea where the edges are. Adjust the angle of … You may have to adjust both screws because one acts as a nut and one acts as a screw. We calibrated the distance between the nozzle and the material first. Turn the laser power off for safety. In the video you’ll see the masking tape caught on fire during the initial firing, which meant we had to do the test again. This week, we're going to be looking at Laser Mirror Alignment on a 50 watt laser engraver I recently purchased. 11. Any distance is fine, but the farther away the target is, the more precise the alignment will be. Since the tube is riding on the gantry, you only have to align the laser on one main axis. Optimise the alignment for the Pockels cell. It may seem counterintuitive, but trust the process. Using the loosen/tighten technique we adjust the mirror mount inward. Not all stages have the necessary precision within their path to be used as optical delay stages. The video illustrates which way the laser will fire as you adjust the mirror holder. Once aligned, move the target to a farther position. In the last 2 parts we aligned two mirror mounts. CAUTION: Use suitable laser goggles and avoid eye damage by never looking directly at a laser beam or its reflection. If you do not feel comfortable performing these tasks, seek professional assistance. It is important to note that just because the end of the laser tube is visible within both mirrors does not mean that the beam will travel along that part. In Part 2, we will continue aligning the 2nd mirror and explain how to use the screws that are used for the minor adjustments. You will see how the large screw is adjusted and the small screw is loosened to move the frame out. When we first turn on the controller, the gantry will automatically try to find it’s home position. share. We want the beam to move up to align it correctly, so we’re going to loosen the large screw just a little bit and tighten the small screw underneath it. This means having to align mirrors on two axes which is far more complicated. We adjusted it a 2nd time to make sure it was aligned well in the center. Address Book, You can change this selection at any time, but products in your cart, saved lists, or quote may be removed if they are unavailable in the new shipping country/region. The way we need to bring the adjustment in is to tighten the small screw. Join Chris Williams as he briefly explains the basics of how to align a laser system onto a target. 4 of 18 Mirrors The three (3) adjustment mirrors used for alignment are on the left side of the engraver. 2. Identical to the Z-Fold configuration, the laser beam should be aligned at two reference points, with the first reference point being at mirror 2, and the second at the target. Covering the difference between a Z-fold laser pattern and a Figure 4 pattern, as well as how to use Edmund Optics laser mirrors with our kinematic mounts. Great to align the laser mirrors. Buy Token for Direct and Immediate Tech Support! So far it has been more challenging to align the alignment tool than to just align the mirrors using the standard approach :). We’ve fired the laser and we can see that we did get it between the circle, but it isn’t quite centered. Two mirrors are directing the laser beam to the dummy Pockels cell. In these tasks, you will find that the laser aligning is quite straight-forward. You have an adjustment here on the first mirror with a hex bolt so it can be adjusted easily. 1 piece of Masking Tape I need a new Target 1. Aligning the Primary mirror. Going Further. In the video you can see that we had perfect alignment on the bottom and middle tests. The reason is some of the screws are for tension and others for adjustment. We’ll start from the very bottom and apply masking tape. Place the mirror on a surface that won’t scratch it. Since we have a good marking we’ll reinstall the mirror. 11. This configuration is generally more compact than the Z-fold. Step 1 – first fire – Move the gantry to bottom as the first picture shows – Do a test fire and have a look at the tape on the 2nd mirror. We’re going to next remove the next mirror and apply masking tape and do the same test as with the previous mirror. Have a fire extinguisher close by just in case! Target (supplied with machine) 4. During my experience in laser labs I encountered many different approaches of how to align a delay stage. I Want to Schecule a One-On-One Paid Tech Support Session, Book an Appointment Pertaining to a BuildYourCNC Product (Free), Book an Appointment Pertaining Other Equipment ($60/half hour), Book an Immedite Appointment Pertaining Other Equipment ($120/half hour), © 2020 PHD Robotics, LLC. Aligning the Galvo mirrors. We’re going to leave the mirror on this time since it won’t damage anything or pose a safety threat if the alignment is off. We also need to make sure the laser is in a straight line, so we raise the nozzle up and fire again. To align the laser with the centre of mirror 3, put a piece of target tape in front of mirror 3 and drive the laser head to the front right hand corner. Home › Forums › Help and How To › How To Align the Mirrors This forum has 2 topics, 1 reply, and was last updated 1 year, 11 months ago by LaserLarry Admin. Rest it on a flat surface. Make sure you are not manipulating the screws of the secondary mirror’s support. The third mirror is on the nozzle and this is the one that moves. Order one by calling 303-215-9171, pressing #1 and requesting part #TT198. For proper alignment it is necessary to understand that from the laser tube to the focusing lens, the laser beam must go straight, bouncing in the center of the mirrors and passing through the center of the lens. There is a nut that keeps the mirror in place. Payment & Shipping Set two points, one as far away as you can get, and one close to the 2nd mirror. One mirror will be reflecting the laser energy from the laser tube. The 2nd mirror is now aligned. Using two mirrors enables you to alter the direction as well as parallel shift the laser beam, making it easier to align the beam expander and Pockels cell. Also note that your mirrors should be cleaned regularly. Once we adjusted again, we had it centered but it was still a little too far right. We are going to jog the gantry from the laser controller using the left and right arrows to position the gantry in the best way to perform the alignment. Next, the laser will be aligned for 1064nm Q-Switched Multimode operation. Align the secondary mirror, alternating adjustment of the screws on … If the beam is not aligned, it will not go through the Pockels cell. On the second firing the location of the beam is now satisfactory, so we put the mirror back on. We have set your country/region to United States. (For Q-Switched lasers, the Q-Switch assembly may be left in the cavity.) In this video we’re going to demonstrate how to align the mirrors on the Vertical Laser XL. We took a photo of the position at each test to compare and see if the laser was still firing in the same place. On a traditional laser cutter and engraver, you actually have two mirrors that move because the gantry has to move away from the laser tube. The resulting beam will be orthogonal to the input beam. In this third and final part we will be aligning the final mirror on the nozzle and then doing a test cut to see how everything is working. Press the laser button just for a second until you see a mark on the masking tape. This alignment process requires two mirrors with the kinematic mounts and two targets with a reticle design on them. To remove smoke, dust, and eliminate flare ups, we are using an industrial dust extractor at one end of the machine and a compressor to produce a high flow of focused air through the nozzle aperature. The mirror numbers correspond directly with the positions on in the bed; for example, if the lens carriage is … Now you will want to make sure the angles of the mirror mounts are correct. You can set the $31 laser mode to cnc mode which allows the laser to fire when the gantry is not moving. At this point we were ready to do a test cut with the machine. The Mirrors I named as “A”, “B”, “C” depends on distance to Reci laser tube. We will again be using masking tape for this test so remember to always have a fire extinguisher on hand. Once the process is done we know that the laser is centered along the top, middle, and bottom points. The beam from the laser can be made to propagate along this axis by using a minimum of 2 mirrors. At this point the machine is ready to go to work. The tasks involved with aligning the Vertical Laser XL involve aligning three mirrors. If the beam hits anywhere outside of the hole, we’ll know with a level of certainty where we’ll need to adjust. Physically move both mirrors to get the laser beam onto a closer position. The Figure 4 configuration also coins its name from the beam path formed by the reflection off the mirrors. Every laser cutter enthusiast eventually pops the question: how on earth do I align an invisible beam that’s more-than-happy to zap my eyeballs, not to mention torch everything else in its pa… In the video demonstration we see the laser hit mostly in the center, maybe slightly low. In Part 1 we discussed the specific configuration of the mirrors in relation to the tube and we fired the laser and demonstrated how to clean the mirror. We’ll start with the first mirror that is reflecting the laser energy directly from the laser tube. The method for aligning a laser using either configuration is the same, so we’ll be using the Z-fold configuration for the tutorial. The Vertical Laser XL is a 4’ x 8’ vertically-oriented lasing and engraving machine. Pictured above is the alignment tool that you will be using to align the Galvo mirrors. You can also use the bottom hole to mount it on an M3 rod (which would need a base of some kind). By adjusting the orientation of the first mirror, the position of the beam at the second mirror’s location can be set. We’ll start the alignment from the tube to the first mirror. After the latest test we found that the alignment was slightly to the right, so we need to adjust the mirror inward.

Attach smaller bracket to the laser head that holds 3rd mirror to align 2nd mirror Insert it into large hole, but DO NOT push it in all the way, just as long as it stays in it’s fine! Finally to attach 3rd mirror alignment tool (larger diameter than , remove lens hosing and insert tool instead). In order to correctly align the laser beam, you have to use the first mirror to align the closer target position and the second mirror to align the farther target position. Now we’ve moved the frame in. Laser Alignment Fusion CO2 Revision Date: 10/10/2013 pg. Using the collimation cap in place of an eyepiece look through the focuser for the 3 clips of the larger primary mirror at the back. We’re going to put a piece of tape on the mirror and pulse the laser very quickly so we can see where the dot hits in the area. Set the Laser head to the top left of work area Hit the pulse button. dba BuildYourCNC.com All rights reserved. stray laser beams. Add a stock number to begin our two-step quote process. Hi, my name is Chris, and I’m going to be showing you an example of how to align a laser beam. Now move the second mirror as far away as … Tighten and loosen the screw on the mount on the nozzle like you did with the other mounts. Now we’re going to apply masking tape. Issue a M3 or M4 S100 to fire the laser. The first kinematic mount should be used to move the laser spot to the desired XY position on the surface of the second mirror. Before you turn on the laser make sure there is water circulating in the tube and the power supply is on. Laser alignment overcomes all these disadvantages and offers a quick and precise method for determining squareness. Two mirrors are directing the laser beam to the dummy Pockels cell. You can take a cell phone camera and view the nozzle through the camera on a smart phone. Please seek professional help if you are not comfortable doing any of these tasks. One method is to use a transparent penta prism in conjunction with a simple alignment laser. In order to correctly align the laser beam, you have to use the first mirror to align the closer target position and the second mirror to align the farther target position. Now fire the laser, remembering to take all safety precautions. Or download and print the CorelDRAW or EPSfile. If the mark was in the center, then your mirror is aligned. Place tape over the second mirror and move it as close up the the laser as it will go. Below, I make 3 tutorial videos how to align laser Mirrors for HL laser engraving and cutter machine. # 1 Phillips Screw Driver 2. The holder has long fingers so that the laser can be tilted, if necessary. The other two mirrors will be static and not move in relation to the laser tube. That dot/circle needs to be aligned. In this video we’re using a non-reflective paving stone between the ribs and then we move the gantry to position it over the stone to make sure it is safe in case any of the beam passes through. This process can be repeated until the user feels the beam is properly aligned to both positions. Then clean the mirror with a non-abrasive cloth.
