Where would I get one of those, I checked my 3 main suppliers (Mouser, Digi-Key, and Jameco) and none of them had it, or atleast I didn't find it. When I did a search on google for it I just got all of those sites that list as many part numbers as possible, and are basically useless. Thanks for the info though. When I bought the phototransistor I am using from jameco I thought it was best for visable light. I'll have to memorize the color wavelengths.
Thanks!
