JCDowdy Posted March 3, 2018 Share Posted March 3, 2018 Added again: Shane, I wonder if we could get Kickstarter Funding for ordering a nice spectro set-up to measure transmission of UV-pass filters, UV-capable lenses and modified camera sensors if we promised to share the data with the Entire World? Do you think we would get any money? :lol: What would we need again? A monochromator, a dual gated something, an integrating sphere, a specro something or other. Argh. I have to go look it up. I've forgotten the terms. FOUND IT: Ideally you need a CCD spectrometer, or spectrophotometer (preferably in a dual beam configuration) with a monochromator, an integrating sphere, and a stable output UV-V-IR source. The integrating sphere helps ensure that the readings are independent of the incoming light ray angle. This will provide you with wavelength specific transmission response. I think I'll go pick out a nice set at Ocean Optics and put it on a Wish List. Any guidance from anyone as to what to pick? Going to disagree with "Ideally you need a CCD spectrometer, or spectrophotometer (preferably in a dual beam configuration) with a monochromator, an integrating sphere, and a stable output UV-V-IR source." Ideally one would adapt the existing ISO method for UV. As we have discussed several times before the single fixed grating array type instruments are inadequate. http://www.ultraviol...dpost__p__12349 http://www.ultraviol...dpost__p__12371 http://www.ultraviol...ndpost__p__6368 Yeah, yeah I know why don't I just do it right? I am not into keeping secrets, having dabbled in the method I just have not got results on lenses that are up to my standards. Link to comment
