The L50(300)A-LP2-65 is a thermal power/energy laser measurement sensor for high power density and long pulse lasers. This sensor also measures air coupled pulses from IPL dermatological sources. It is similar to the L50(300)A-IPL but does not have the window so is for air coupled sources only. It gives the most accurate measurements for air coupled sources. It has a 65mm aperture and can measure from 400mW to 50W continuously and to 300W intermittently. The sensor can measure energy from 200mJ to 1000J. Its 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.
