Laser Power Sensors

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

Round Photodiode Sensors – 20pW to 3W
Similar to the standard photodiode sensors where cylindrical geometry is preferable. Fits SM-1 threads.

High Sensitivity Thermal Sensors – 30uW to 12W
Very low noise and drift thermal detectors accurately measure low powers over a wide range of wavelengths. Will also measure low single shot energies down to tens of uJ.

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

Low – Medium  Power Thermal Sensors – apertures to 35mm,
30mW to 150W
Sensors for low powers or intermittent use up to higher powers for pulsed or CW lasers.

Medium  Power Thermal Sensors – apertures 50mm to 65mm, 200mW to 300W
Sensors for larger beams and higher powers. Compact sensors for intermittent use.

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

High Power Water Cooled Thermal Sensors And Power Pucks - 4W – 10KW

High power water cooled and fan cooled laser beam dumps
Water cooled sensors for highest power

Special Photodiode Sensors
Integrating spheres for measuring divergent beams, flat response detectors for broadband sources, eye response detectors for Lux measurements, peak detector for measuring scanned or chopped beams.

Comet Portable Power Probes
The low cost Comet power probes are perfect for laser job shops. They give simple and accurate power measurements up to 10KW and 10KW/cm²
