The L50(150)A-LP2-35 is a thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 35mm aperture and can measure from 100mW to 50W continuously and to 150W intermittently. It can measure energy from 40mJ to 3000J. The sensor is able to measure high power lasers of up to 4000W by measuring the energy of 0.4 - 4s exposure to the laser. The high damage threshold LP2 absorber covers the spectral range from 0.25 to 2.2µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.
