Hi Gekko,

Thank you very much for your greeting, I often view thru many of your beautiful photographs and other members in the forum. It is very interesting. But I am not post much because of my laziness.

I saw some discussion of LED illumination adapt into microscope. The UV Filter may need in some case that we don't know the output spectrum. But for normal white LED, I think it need not to use UV Filter. The normal white LED ouput close to zero UV in the sprectrum band.


Best regards,
