    You can order them directly from us by mail to info@swisslas.ch

    But yes, deliverytime will be middle - end of July because our stock is empty!

    Important difference with our prisms is that ALL 4 SIDES are AR coated speciall for 445nm and speciall for this expansion ratio (angles), so this is the reason why there are directly glued to the holder!
    You have a total loss of only about 7%!

    AND The Result with Cylindrical lenses is much bader then with prisms! We made a lot of tests with this two years ago.

    According Prices:
    The Prismpair with holder costs 110 CHF (with acutal exchange rate about 100USD)
    The collimating lense (loss 1%) in M9x0.5 holder costs 65CHF (with acutal exchange rate about 60USD)

    transportcosts from Switzerland to outside Europe with Priority service is 26CHF (about 23USD)

    i emailed swisslas got no reply as yet ,so they can not be that keen to get orders
    mayby you can give them a kick

    Completely understandable. Maybe a groupbuy for the extreme good quality collimators.

    I will have 5 modules ready to build 5 dual blue,s. Designed to hold your collimators and tec cooled including table for the prism pair. I ordered 5 prism pairs with p1t8ull.

    if you want a module completely anodisized let me know.

    I will have a few prisms coming in as well, likely same price or cheaper, it depends on how much customs will charge. May arrive in a few days, hopefully.

    PS: These prims are AR coated specifically for 445nm and for 56 degrees incidence at the angled side, unlike the ones of the group buy, so they should provide the lowest possible loss. I will perform measurements as soon as I get them.

    Today I have received some prisms and because a few people who had asked me for some, have in the meantime ordered via the group buy, I got some leftovers.

    The data are as follows:

    Material: K9 = BK7
    Size:7.81216
    Wedge: 33 Coating:AR/AR
    Surface Quality:60/40 Flatness:lambda/4
    Coating AR/AR S1:AOI=0,AR440~450 coating S2:AOI=56,AR440~450

    They are coated on the sloped side for incidence angle of 56 degrees, so very little loss is expected when using them at or near this angle. Just right now I have made carefully some measurements and indeed found that at proper adjustment, the total loss is about 3% (when changing the magnification by turning away from that angle, the losses grow). A movie that shows this is here: http://pagesperso-orange.fr/redlum.x...cs/anamorp.MOV


    A pair goes for $30 plus shipping. First come first serve.

    I'd like to purchase two sets, if possible.

    I'll take a pair if a set is still left. Well, depending on shipping from your location.

    Hi all, already sold out it seems, the first ones got PM and there are no ones left for the others - in case of cancellations I would notify the next in line.

    Thanks for your interest!

    Regards,
    Wolfgang
