 One of the most common but unfortunately confusing aspects about maintaining your laser is that the colors can get misaligned. In this guide, we will discuss what kinds of misalignment can happen, how to best avoid misalignment, and then show you how to re-align each type of alignment mount. One of the most common but unfortunately confusing aspects about maintaining your laser is that the colors can get misaligned.

 If you are aligning the beam on site, or cannot get a bounce or a friend to call the movements out, using optical magnifiers like binoculars or a spotting scope can help get a good view of the beam at a great distance.  If you are aligning the beam on site, or cannot get a bounce or a friend to call the movements out, using optical magnifiers like binoculars or a spotting scope can help get a good view of the beam at a great distance.

 If you are opening a laser, and especially a module, to do an alignment, it can be easy to accidentally use a reflective tool and shine full power beams all over the place. We recommend all users, but especially beginners, use some sort of power-reducing eyewear to reduce their risk while aligning. The recommended pair of eye protection for this kind of job can be found on the Pangolin website: If you are opening a laser, and especially a module, to do an alignment, it can be easy to accidentally use a reflective tool and shine full power beams all over the place.

 Sometimes digital tools which can display your beam on a screen can be a useful less eye straining then looking directly at the beam. Often these setups are used by the manufacturers in their production to ease the strain on their employees and sometimes even get more accurate then the average eye can. One of the easiest solutions to get into this technology is with the **Beam Analyzer**, which can be purchased on the Pangolin website. Sometimes digital tools which can display your beam on a screen can be a useful less eye straining then looking directly at the beam.

 === Make Sure Your Optics Are Clean === === Make Sure Your Optics Are Clean ===
Line 215: Line 218:
 Before performing an alignment, it is best to ensure that your optics are clean and free of any debris.  Dirty optics can lead to issues with the output that make alignment more difficult and, in worst case scenarios, could cause damage to the optics while the laser is on.  Laser light passing through optics should generate little-to-no scattering or "shine". If the beams seem bright when they pass through a dichroic filter or the output window, that optic is likely dirty.  Please refer to our guides on cleaning your optics to ensure they are clean before performing alignment: Before performing an alignment, it is best to ensure that your optics are clean and free of any debris.  Dirty optics can lead to issues with the output that make alignment more difficult and, in worst case scenarios, could cause damage to the optics while the laser is on.  Laser light passing through optics should generate little-to-no scattering or "shine".
