    Default 445nm specific PBS cube GB

    Is there any interest in a PBS cube, specifically for 445nm?

    For 445nm, the loss can be less than 2% sometime, but sometime it would be higher than 2%.
    For 445nm, we can guarantee the coating specs listed bleow:

    Tp>97%, Ts<1%
    Rs>99%, Tp<3%
    these are a 10mm x 10mm x 10mm cube, specifically coated for 445nm

    Price would be $35AUD if I can get 100pcs - This includes shipping and PP fees

    Ill start ;-)

    Dave: 10pcs

    Do you know the bandwidth on the coating? Or even better... have a full T/R plot for each Pol. over a 445nm 15nm?

    Lemme know if / when you do a run of 12mm x 12mms.. I am sure there are a few of us 'high-power gluttons' that will buy, for larger-powered arrays.. Also, 12mm ~ plates for 445..

    cheers..

    Yeah, 10mm x 10mm is the only thing sort of holding me back. My old eyes kind of like larger parts.

    Aswking questions about 15mm x 15mm x 15mm cubes

    Specifications are as follows:

    surface quality: 60/40
    flatness: lambda/4 at 633nm
    beam deviation<3 arc minutes
    parallelism< 3 minutes
    AR coating at 445nm on all the four input and output surfaces, R<0.5%

    When asked about bandwidth of the coating, I recieved the following reply:

    Yes, we have a bandwidth of the coating. For PBS at 445+/-15nm, the specs are as follows:

    Tp>95% at 445+/-15nm, Rp<5% at 445+/-15nm
    Ts<1% at 445+/-15nm, Rs>99% at 445+/-15nm

    Sweet; cheers.
    What's your time scale on this GB?

    OK, some more info.

    Time scale - depends on how we go with qty's I guess

    about bandwidth, I asked, and this is what i recieved:

    PBS at 445+/-15nm
    Tp>95% at 445+/-15nm, Rp<5% at 445+/-15nm
    Ts<1% at 445+/-15nm, Rs>99% at 445+/-15nm

    PBS at 445nm
    Tp>97% at 445nm, Rp<3% at 445nm
    Ts<1% at 445nm, Rs>99% at 445nm

    About bigger sizes,

    15mm x 15mm x 15mm would be $40AUD inc airmail shipping if we can get 50pcs
