Hi all, I'm considering use of an IR sensitive sensor (9 to 13 uM) in a project.=20 Before I commit, I'd like to know if fluorescent lighting can interfere=20 because it might have output in the 9 to 13 uM range. All the web=20 searches I can find give spectra output information in the visible and=20 near IR ranges only. Does anyone have info about this? Thanks, Art --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
