    Hello Boys.

    Is there anyone here who can help me. I would like to combine one 450nm and one 465nm diode, which dichroid should I use?
    Both colors are cubed of 2 diodes. color combination

    you may have to get something custom made... what's you budget?

    Several folks (Lasershowparts and Stanwax for example) used to sell dichros that worked well with 473nm and really poorly for 450nm, but I don't know where the 'line was drawn' spectrally speaking. I'd suggest testing one of those before doing any custom work.

    I have a couple but you have to pass the 445nm at 80-90degrees and reflect i the 465nm

    Cause they're already cubed! ("Both colors are cubed of 2 diodes. color combination")

    Knife them in pairs and cube them, then prisms, or go the expensive dichro route.
    You'll need to offset the 2 wavelengths very slightly into the prisms to ensure they overlap on the way out due to the wavelength difference. Should be very small though. Its not much, even with 462 and 520.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.
