Thermal Sensors, Low Power Laser, up to 40W CW

Manufacturer's part number :

Low Power Laser Power Meter

Manufacturer LaserPoint


Description :

Thermal Laser Sensors with High Sensitivity for very low powers: 10µW to 2W. Low noise and low drift thermal sensors that accurately measure low laser powers over a broad wavelength range. They can also be used to measure low single shot laser energies down to 200µJ.

Low Power Thermal Sensors: 10mW to 40W (200W short term). Laser Point has a selection of measurement sensors for low average laser powers, for continuous or pulsed sources having beam sizes up to 60mm. Sensors are so robust that a version of the 40 W model can be safely used up to 200 W.
