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 Power Sensors introduction»

Laser position sensor | Size measurement

BeamTrack series Thermal Sensors 100µW to 1000W
Thermal sensors that measure laser power and single shot energy like standard thermal sensors but in addition measure laser beam position and laser size. This position sensing detector measures laser beam position to 0.1mm accuracy and laser size measurement of a Gaussian beam to +/-5% accuracy. Measuring laser position is important for laser alignment where the laser position sensor can provide feedback to the laser position control.


Laser Photodiode Sensors | Laser measurement sensor

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.

Laser Thermal Low Power Sensor | Laser measurement sensor

High Sensitivity Thermal Laser Sensors – 30uW to 12W
Very low noise and drift thermal laser measurement sensors accurately measure low laser powers over a wide range of wavelengths. Ophir’r thermopile sensors also measure low single shot laser energies down to tens of uJ. 

Low Power Thermal Sensors – 20mW to 50W 
Ophir has the widest selection of laser power measurement sensors for low average laser powers in the industry,  pulsed or continuous laser sources and various beam sizes.

Laser Thermal Medium Sensor | Laser measurement sensor

Low-medium power thermal sensors - apertures 17 to 35mm, 30mW-150W 
Laser measurement sensors for low laser powers or intermittent use up to higher powers for pulsed or CW lasers. 

Medium  Power Thermal Sensors – apertures 50mm to 65mm, 100mW to 300W
Laser power sensors for larger beams and higher laser powers. Compact laser measurement sensors for intermittent use.

Medium-High Power Fan Cooled Thermal Sensors -50mW to 500W
Compact fan cooled Laser measurement sensors for continuous use at higher laser powers

Laser Thermal High Power Sensor | Laser measurement sensor

High Power Water Cooled Thermal Laser Measurement Sensors And Power Pucks - 1W – 30kW

High Power Water Cooled and Fan Cooled Laser Beam Dumps
Laser beam dumps for high power laser processing, laser measurement and other applications
