More Alignment Practice

 I did some alignment at the beginning of my internship to make sure that the lenses, camera, and other optical components I was working with were in the right place. Meanwhile, another intern has been working on getting a Spatial Light Modulator Set Up. This week, they brought it upstairs to integrate it into our system. That means doing the alignment all over again to make sure each mirror, lens, filter, and the spatial light modulator itself are in the right place. Once we roughly position the mirrors we work with, we pick two mirrors and "walk the beam" by making small adjustments to center the laser with one mirror, and then correcting its position with to other.
