UV Filter to mix in blurays?

[Frixxion]

I read about using standard UV-filters for camera's to create an RGV projector. But is that really possible? It seems plausible since blurays are very close to UV. I thought I read about this in some thread here at PL, someone sayed there are able to reflect 95% . Maybe I'll buy one tomorrow since they are so cheap .

So does anyone know about this? Anyways I'll keep you updated if I find out anything

I use a UV reflective piece of glass in my RGBV... I have the 405 dichro but it doesn't fit in my optics holder well so I used this instead. Seem to be more efficient with the angles I am using.

I am not sure if what I am using is the same as a UV filter...

UV coated glass .. AKA a UV filter for a camera>????

some camera filters are dichroic and reflective, if you can find one, thats good.

If they are the adsorbing type, it does not work.

With the dawn of CCDs, UV filters are kinda fading into the past, but they were useful for color film in flourescent light or metal halide or sunlight.

PM a member here named bridge and ask him who his European dealer is.

He sells UV dichros and combining cubes

No idea; it was in MarioMaster's FS thread, http://www.photonlexicon.com/forums/...ead.php?t=5577.

Says UV mirror.

It should say UV dichro.

Well, I'll see if I can get a UV reflective glass overhere in the local camerashops and see if they work.

I'll keep you guys posted!

, UV filters are kinda fading into the past,

Nowadays they are merely used as an affordable first line of defense for dirt and scratches.

hell CCD is on its way out to for CMOS (complimentary metal-oxide semiconductor)

CMOS has a long way to go to catch CCD. CMOS is used in low end consumer grade gear because you can get a used CMOS chip fab in Taiwan and adapt it to cameras for next to nothing. CCD still wins in linearity,dynamic range, gamma, and sensitivity.
