hello all, I'm looking for a material, preferably a 5" glass plate, that I can use to cut out <350nm wavelengths ( I really only need to cut out the 334nm peak) from my aligner. Can anyone point me in some direction? I have found a glass on Schott called wg320 which I could have an optical film put on to cut out the 334nm peak. Does anyone know of a vendor that can provide this service for a small lot (one piece) at a reasonable price (Melles Groit would charge in the 1000's)? thanks in advance, eric
