Description:
The L300W-LP2-50 is a water cooled low profile thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 50mm aperture and can measure power from 0.5W to 300W and energy from 200mJ to 300J. Its high damage threshold LP2 coating covers the spectral range 0.35 – 2.2 and 10.6µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.
