    It's a BIG trichro cube that Buffo brought.
    Here's another shot of us messing around with a Fujinon trichro. IMG_3717.JPG
    Note: that "green" line is actually 568nm "yellow". Ar/Kr into the trichro vs. RGB solid state kind of gave a neat sense of how the trichro elements were coated.
    And another:

    That's pretty cool. What are the losses like through that thing?

    Subjectively, the losses didn't look too bad, but on further inspection we saw interesting things happening like very dim Ar and Kr green bleeding through the "blue" port and none coming out of the "green" (yellow) port...Like I said- very interesting coatings! Did some very rough characterization with a handheld spectrometer, but we were mainly concerned with confirming which greens were bleeding through with the blues.
