Collecting the total radiant power emitted by highly divergent or collimated sources.
Liquid-cooled Laser Power Measurement Spheres include three sizes of liquid cooled integrating spheres, designed for performing power measurements of high power pulsed and continuous wave lasers. Coated with InfragoldŽ high reflectance coating for measurements over the 700 nm - 20 ėm wavelength range, the liquid-cooled design can handle a maximum power density of 2 kw/cm² (CW for 1 second exposure at 10.6 ėm) while greatly reducing the self emission that would result from an uncooled sphere.
