Special Photodiode Sensors
Description:
The BC20 is a photodiode sensor for measuring scanned or intermittent beams such as bar code scanners. It has a swivel mount and a 10x10mm aperture. It covers the spectral range 400-1100nm and its power measuring range is 0.1mW - 20mW. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.
