The L40(150)A-LP2-50 is a thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 50mm aperture and can measure from 300mW to 40W continuously and to 150W intermittently. It can measure energy from 100mJ to 10,000J. The sensor is able to measure high power lasers of up to 10kW by measuring the energy of 0.3 - 2s exposure to the laser. The high damage threshold LP2 absorber covers the spectral range from 0.25 to 2.2µm and 2.94µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.
