Spectrometers for Laser Measurement. These miniature rugged spectrometers are calibrated to measure and track laser frequency and centroid wavelength and/or total power of lasers in Watts. Currently, StellarNet offers laser measurement systems in the 200-2300nm range.
IMHO, there is no absolutely no reason ordinary people should own a laser pen this powerful. First of all it's miliWatt, mW. Secondly, that's optical power, not electrical power. at 200mW optical power, the reflection off a shiny surface has the potential to blind you, and so does staring into the beam. If the wall plug efficiency of the laser is 6%, that means that the electrical power draw is 3.33W.
