    Smile UPDATED : lower price!! Dichro for 445 + 462nm mixing

    UPDATED : found another source with even cheaper price, but efficiency is just a bit less good (still very good).

    This is a great opportunity to have a very interesting price for a dichro to mix two different blue wavelengths regardless of polarization.

    If we reach min 20 pcs the price would be 90€ excl. VAT. (102.50 USD)

    Details :

    - HR : 460-470nm
    - HT : 430-450nm
    - Efficiency : reflection >95% / transmission >90%
    - Size : 10x20x3 mm
    - AOI (angle of incidence) : 45

    Dichros will be shipped from Austria, so for EU members 20% VAT will be added to the price (total = 108€). For non-EU members : no VAT.

    Payment : Paypal (+4%) or bank transfer.

    Who's interested?

    I've been out of the loop on this for some time. How are people combining them now? PBS? And, what's the efficiency of current methods as compared to this dichro?

    You can for sure use a PBS to combine two different wavelength of blue but to properly make that you need 1x mirror, 1x waveplate, 1x PBS (so, 3 mounts).

    AND of course with a PBS you can only combine two polarized beams, this is where a dichro is useful if you want to keep great beam specs at higher power.

    With the dichro method, you can combine one non-polarized quad of 445nm with another non-polarized quad of 462nm, and end up with a 12W, <5mm and <0.8mrad blue beam

    Thanks. My guess is, as this list of interested people grows I'll be adding my name.

    Hehe nice to hear, for that price it's really a bargain, usually prices are more in the 3-400€/USD range! 120€ is even less than the cost of a good PBS + waveplate...

    any chance of getting these in a round/mounted configuration?

    I don't think so, only rectangle version... haven't you an extra brass mount other there to mount those rectangle optics?

    Sort of interested... Would be far more interested at 100 USD pricing. I'm quite aware that your price is very reasonable, compared to say, Semrock...

    I use the ones from Semrock and they work well for the 45degree AOI, but If anyone wants some that are coated for 90degree AOI, let me know, I have about 10 I can let go of for $100 each if anyone is interested.
