Zom-B said:I've analyzed the basic optics more thoroughly.
The PBS cube is transparent for RED and IR always, and reflects between between 5% and 95% of violet depending on polarization. For green, it seems to reflect between 1% and 10% depending on polarization.
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?
