Hi guys! How can one measure the wavelengths, either a graph over the spectrum or certain wavelengths of a UV-source? What unit would one use - Watt, Joule? I have a few colormeters but those are for human visible light intended for graphics industry. We use candela, cd, or lux for intensity there. I've found this: http://www.oceanoptics.com/products/usb4000uvvis.asp "Priced from $3,061" Ouch .... Next question, what wavelengths are of interest here - different wavelengths for different materials I suppose? 300nm? I'm currently curing UV-inked paper with two 160W disco Blacklights but I'm shure I could do it more efficient with other sources. The paper let the ink go deep into the material so the UV-lights/leds in the printers does not really let the ink solidify. /Per Per Mattsson - per@permattsson.se - +46706524567
