Laser power sensors

Ophir provides two types of power sensors: Photodiode sensors and Thermal sensors.

Photodiode sensors are used for low powers from picowatts up to hundreds of milliwatts and as high as 3W.
Thermal sensors are for use from fractions of a milliwatt up to tens of thousands of watts.
Thermal sensors can also measure single shot energy at pulse rates not exceeding one pulse every ~5s.

  • Laser Photodiode Sensors

Standard Photodiode Sensors - 10pW to 3W

Ophir Optronics, Photonics, Photodiode sensors, Cheos Oy,PD300

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.
