    anyhow, I am definitely down for a pair of 445 plates if you still have those multi-diode setups available
    Tell me about it! The day CNI quoted me on a 532nm module I replied stating "I need to pay you today!!!!". $1.05 exchange rate!

    I'm interested in 2x 640nm maybe more.

    Also interested in a couple of 650nm waveplates.

    but can you be a little bit more clear about "very little loss"
    I still remember the old laserwave dichro's with "very little loss"

    Is it possible to get thicker waveplates? as a 0,5mm wave plate can break very easy

    Default wave plate questions

    how is a wave plate set up for use ??
    does it need to be the right way around to use ??
    does in need rotating so the polarisation is correct for use with a pbs ??
    will it need a special mount to acheive the above ??

    if anyone could let me know the rules to using one of these would be cool
    When God said “Let there be light” he surely must have meant perfectly coherent light.

    from what i understand, you just treat it like a normal, plain piece of glass.
    it does the rest by itself

    It would be nice to have it a little bit thicker. Half a millimeter is very thin

    A mm would be perfect. I can turn the diodes in my setups but for blue it would be nice to build a 8 watt of blue just for fun. I,m thinking about two sets of 445nm.

    Dave's list only states 640nm or 660nm...


    Anyway,
    Put me down for:
    - 2x 445nm
    - 1x 640nm
    - 1x 660nm


    What is your planned time scale on this?

    Cheers Dave,

    Hi Dave

    I'd like to register interest for the following halfwave plates...

    3 x 640nm
    3 x 532nm

    However, I too wonder if you are able to get these made slightly thicker (~1mm) as 0.50mm is pretty thin and easily broken, something slightly more robust would be good .

    Perhaps you could find out and let me/us know and then I can make a decision as to whether to confirm/cancel the order.

    Cheers
