    I think they are at the post office3 for me to pickup today. It will be by eye since I don't have a power meter but I will post the results. I got three sets so I'm changing out my other dichros as well.

    I got the dichro and now have to build the projector. Got the mechanicals done yesterday and hope to do the electric today. My lava drivers came. Look slightly smaller than I remember but I think that is the darker color pcb. Anyway. Test coming once built.

    Hi Junk,
    Any news about other wavelength test? .
    Best regards!

I should be able to test with these lasers in the next few days. Deep blue and red may have to wait until I have the new Brightlight laser projector here.

    If anyone is seriously interested, I could also test with a 577nm yellow Taipan. From the graphs, it's clear that Dichro A will not work at 45 degrees, but I can see if it works acceptably at a shallower angle.

    Any reason to test these at 405nm? Didn't think so

    going to be a while for me before I am ready to test the dichro at 520nm. Just too busy with life right now.

    Sorry to hear you will left laser for a while, but, yes, life is more important than lasers, .

    All,
    I found some time this afternoon to test both dichros on a 515nm source.
    Results are very comparable between the two at 45deg AOI, 0.3% difference maximum.

    Type A is quite angle sensitive at 515nm, but peak performance is very close to 45deg AOI.
    Transmission test:
    NO Dichro = 3.18W (60 sec average)
    Type A = 3.09W ~ 97%
    Type B = 3.10W ~ 97%
    Both close to 45deg AOI, Type A may be +/- 2 deg to peak it.
