Nis300zxsan Posted April 2, 2012 Posted April 2, 2012 I was wondering if there is a power meter with detector that can accurately measure under 1 picowatt in the visible range 200 to 1100nm?
John Cuthber Posted April 3, 2012 Posted April 3, 2012 Yes, there are detectors that can count single photons in the visible range. Though 200 to 1100nm is an odd definition of that range. http://en.wikipedia.org/wiki/Photomultiplier#History
