    Nice to hear, maybe we could reach enough interested peoples to make this happen

    Don't know how they work at 488, will let you know as soon as I get the info.

    Nice to hear, have you an idea of how much you could buy?

    About 488nm, usually those dichro are highly AOI dependent, so maybe by increasing a bit the AOI, efficiency could become great at 488nm... Still waiting on the answer from manu...

    If they renew my contract here, at least two. If we haul in my non-PL friend who wants one high power system, at least three...

    I'm in for 2 pcs, how much exactly all of you interested peoples above would you like? Maybe we are not that far...
    you can use a PBS without a waveplate... I use a PBS alone to combine 445/473 without issue

    with the new manufacturer is round a possibility?

    Sure but this way you have to rotate one diode 90 compared to the other one, ending with sort of a cross pattern, with one fast axis on each direction, not really the cleanest solution...

    Yes you could have a round optic, but you need to order 50 pcs I'm afraid this run is only for rectangle shape, as the dichro manu will make a custom run of only one shape. But have you considered the several other types of "small mounts" available out there? There is more clever solutions than the cheap brass mounts, like the one I'm using into this projector (spring based 4-axis) :

    that's an adorable mount but probably out of my price range

    for beams I don't think the + shaped beam will really matter much... but I am using it to combine 445/473 so the 473 gives me a nice round dot anyway

    No they are really not that expensive, around the same price than the usual brass mount, I can ask for details if u're interested

    Just got the answer, you can have these mounts for 15€ together with a dichro ! Really not in your price range?
