Ok, so I have this projector out of a planetarium that was put together by the theater and I think they might have made a bit of a mistake. I'm wondering if there's anyone out there with a similar configuration. I lack a power meter so I can't take any real measurements. Basically, with everything aligned I'm assuming the waste beam is probably around 60% and the 1st order beam around 40%, maybe less. So I did a little research and found that the model PCAOM I have is designed for a horizontally polarized beam. Somewhere around here I think I read that the laser is vertically polarized.
So if you have a similar setup, which PCAOM do you have and how is it oriented?
