ThomasNet news
August 13, 2009 - Designed for laser beam measurement applications, Models SP503U and SP620U accurately capture and analyze wavelengths from 190-1,550 nm, both continuous wave and pulsed mode. Cameras have resolution of 640 x 480 pixels and 1,600 x 1,200 pixels, respectively. Able to synch up to 1,000 Hz, built-in photodiode trigger includes firmware that analyzes background lighting and provides offsets, allowing triggering on variety of energy levels, including energies down to 10 µJ.
