The FL250A-LP2-DIF-33 is a fan cooled thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 33mm aperture and can measure power from 400mW to 250W continuously and energy from 400mJ to 600J. Its high damage threshold LP2 absorber covers the spectral range from 0.4 to 3μm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.
