Efficiency of a Tricho ?

[marconi]

Kewl ..Sounds like what Im seeing here as well

I have two different sizes of Fuji's here
The tiny one that I got from Spec is 10mm by 12mm on each of the RGB faces
It has less loss but very small.


The larger one pulled from a Sony Betacam is 18mm by 22mm output face
aprox 22mm .. larger and easier to use.

The HUGE one pulled from an RCA film chain is too big to use and extremly lossy..Its justa show piece.



The smaller one has less loss , however I dont remember just how much less


Still..All very usable..

Wow! That last trichro you've got is friggin' *huge*!

Can't imagine what a laserist would use that for... Maybe if you had to combine a few *really* high power lasers and you were worried about blasting the AR coatings off, you could enlarge the beam diameters first, then pass them through the trichro, and then shrink the white light beam back down again... But that seems like way too much work.

As you said - it's better as a show-piece. Or a door-stop!
