The long mirror is for all three intended wavelengths exactly 50% reflective, non polarized, non dichromatic. For green, it is totally useless as internal reflections create a strange fanning/repeating reflection. So ultimately it is dichromatic, but not in a usable sense.

The 90 mirror is of course reflective for all intended colors, but not for green. Again, internal reflections make it useless for this wavelength.
So does the PBS pass most of the green light?

ok so i wanna get this right. The cube is the psb. The long rectangle is a mirror. and the square with a angled cut on one of the faces is just a 90 degree mirror. Is all that right?
