Laser Photodiode Sensors

Standard Photodiode Sensors - 10pW to 3W
Ophir's Laser Measurement Photodiode PD-300 sensor series measures laser power with spectral coverage from 200nm – 1800nm, and automatic background subtraction so the laser measurement is not sensitive to room light. All models have wavelength calibration built into the system.

Round Photodiode Sensors – 20pW to 3W
Ophir's Laser Measurement Round Photodiode sensor series measures laser power similar to the standard photodiode sensors where cylindrical geometry is preferable. Fits SM-1 threads. 

Special Photodiode Sensors
Integrating spheres for measuring laser power of divergent beams, flat response sensors for broadband sources, eye response detectors for Lux measurements, peak detector for measuring scanned or chopped laser beams. FPS-1 sensor for measuring temporal laser response into oscilloscope with 1ns response time.
