The L30C-LP2-26-SH compact OEM thermal power and energy sensor is for use freestanding or mounted to a host system. It has a 26 mm aperture and can measure laser power from 300 mW to 10 W stand alone and to 100 W when heat sinked. It can measure energy from 30 mJ to 2000 J. The sensor is able to measure high power lasers of up to 4 kW by measuring the energy of 0.5 to 4 s exposure to the laser. The high damage threshold LP2 absorber covers the spectral range from 250 to 2200 nm. The sensor comes with a standard 1.5 meter cable for connecting to a laser power meter or PC interface.
