Today, I came back to the lab and found out that we had some PVA sent to us already stretched and treated. It was in a large roll attached to plastic backing for strength. Unfortunately, it has not worked well as a polarizer so we have to continue to find a better solution. For the other project of the vortex lens, we went over to the microE building and learned how to use another tool, which almost wraps up the training. Other than that, it was a pretty slow day. Tomorrow I have the Imaging Science class so I will only be in in the afternoon.
