where to buy collimating optics ?

[Zoof]

As title for 200+mw red and blu-ray diodes.
drlava pointed out that the AR coated glass lenses for red diodes reflect 405nm light so plastic lenses are preferred for bluray diodes.

Roithner sells lenses but are pretty expensive. The Aixiz housings with glass lens seem to work well with red but not so well with violet.
What is a good place to get both the M9 0.5 pitch glass and plastic lenses.

thanks

Hi Matthijs,
yes, the red pointer lenses always coating single wavelenght AR, so at 405nm this mirror always with large reflection, but plastics always not the best, as many plastics absorb light, especially the 405nm, which is very near the UV light. I don't know CCD lenses is right for your use, this unit is always coating broad band eyeable wavelength.
Best regards!
