    Question is how many people interesting those dichroic? as you know for coating, more small quantity meaning more expensive.
    If we can catch 100pcs or more, with reasonable prices, sure, we can do.
    Best regards!

    On here I'm guessing just me or maybe one or two others with Kvants or who are building projectors using Kvant modules. Worldwide, who knows. How many Kvants out there?

    One thing you could do is talk to Kvant. I don't know who there supplier is, but I'm guessing there's a trade deal to be done at the right price. They're very high quality projectors but I don't think they've gone to town with the dichros. I don't have anything to take measurements from but there is a highly visible beam of red / blue passing through the mirror and a similar highly visible beam of green passing through the pass red blue reflect green dichro. I feel pretty sure based on the brightness that whatever they're using atm doesn't come close to those figures.

    Are these available in 25mm. I have the VM1 mounts

    Cheers

    25mm we had some in stock but not much, the same time, 25mm is more expensive than 10*20*2mm.
    Consider you are in UK, please contact with Rob(Stanwaxlaser), he always had some in stock.
    Best regards!

    10W 532nm test results

    Millennia Xs power after 30 minute warm up = 10.15W

    Transmitted power with Dichro A (reflect red)
    45 degrees - 9.90W (97.5%)
    60 degrees - 9.96W (98.1%)
    30 degrees - not usable

    Transmitted power with Dichro B (reflect blue)
    45 degrees - 9.82W (96.7%)
    60 degrees - 9.87W (97.2%)
    30 degrees - 9.46W (93.2%)

    Thanks Junk,
    So at least from 45-60 degree is high efficiency, look like no worry about tunable problems.
    Best regards!

    I tested "real world" lasers on the dichros today, results below:

    Results are within ~1% agreement to Kevin's results and my spectrometer measurements.

    All tests were performed at 45° AOI, and average transmissive results quoted when appropriate, as they always tend to be lower, in comparison to reflective measurements. Assume S+P polarisation for all lasers. A Coherent LabMaster Ultima and an LM-10 head (with wavelength compensation) was used to take the measurements.


    Wavelength / No-Dichro Power / With Dichro Power / Transmissive or Reflective Test / Efficiency

    Type A:
    445nm / 1.73W / 1.58W / T / 91.3% (More than likely irrelevant if used in a R red, T green manner )
    532nm / 6.61W / 6.35W / T / 96.1%
    638nm / 1.65W / 1.64W / R / 99.4%

    Type B:
    445nm / 1.72W / 1.70W / R / 98.8%
    532nm / 6.62W / 6.40W / T / 96.7%
    638nm / 1.66W / 1.62W / T / 97.6%


    Overall these are genuinely quite great dichros.
    If we assume a last to first order before galvos of the lasers, Green, Red, Blue, and Type A then Type B for the dichros:
    Superb coupling of blue
    Superb coupling of red (especially as this is currently the "most expensive" colour mW for mW)

    Satisfactory 532nm green coupling.


    Is there any interest at the direct efficiency at 515nm? The spectrometer reading indicates it would be very good.

    - There is no such word as "can't" -

    VERY VERY VERY interested in 510-525 range.

    So both types are reflect red dichro? Thought one would be reflect red and one reflect blue.

    one is reflect blue.the other is reflect red
