    if any of you dont need the dichro's , after testing them, i will be more than happy to purchase the set (of course, after you do the review on them.)

    yes, I can read! good dichros have no differences between H & V polarisation of a laserbeam.
    the reflectance of all SwissLas dichros is near 100%
    the transmission of green is much difficulter then the transmission of red!

    definitly! I can proof the loss of about 1%....
    you will not be happy if you only reading the datasheets!

    Anyone here done a test on the reflect red pass green laser-wave dichro's? Are they any good? I asked because I have one just about at my door, though don want to be loosing heaps of my precious photons

    Yes I have done tests of all laserwave dichro's except the bluaray one because I stopped playing with bluray as it will not increase the brightness of you RGB system, anly makes your RGB system more dangerous...


    ps Phil's dichro is about 1/3 of the price of a swisslas.

    I will be happy to test the Swisslas dichro's, if they have less than 1% loss on pass trough on red and green I will pay them, If they have more loss than 1% loss I will keep them for free.

    Deal?

    (235 + 50) > 272, so there is something wrong with your measurement setup (or those scanners are **Stupid** lossy)....

    yes that could be!

    but if you have a 1000mW RGB Laser each mW costs about 3.5USD
    if you have 1% loss insted of 4% loss you will safe 30mW which costs more then 100USD so it's no problem if you pay a bit more for the dichroic filter!

    you ever told only about the loss of red.... this is 1% the loss of green is higher, but not more then 3% but it's very hard to measure the loss of green light because you have not a stable green laser and you need a ververy good IR filter to measure the power (and I have not a good stable green laser too for my measurements)

    But we can do this deal only for red! because this is easier to measure! and I see you have a good quality power meter!

    I absolute agree with you Vacuum.

    The reason you gave about the difficulty to measure with green thats why I didn't post the results with green. But I have tested it and I also used a IR filter in front of green.

    The losses of the laserewaves are less with green than compared to red.
