Ah! That's the photo-negative enlarger you posted earlier. I used exactly the same one but in a very different setup. So you use it (not like me) also for rack focusing?

It's also called anti-reflective glass and sometimes UV-glass, but than you have to be sure it has an anti-reflective coating too.

Yes, the second lens is also to squeeze the image to the opposite side, but a prism close to an object seems to behave very differently. For instance, you have to rotate it 90 deg. otherwise it'll...
