Cooled Laser Power Measurement Sphere

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 Infragold® high reflectance coating for measurements over the 700 nm – 20 μm wavelength range, the liquid-cooled design can handle a maximum power density of 2 kw/cm2 (CW for 1 second exposure at 10.6 μm) while greatly reducing the self emission that would result from an uncooled sphere.

Uncooled Laser Power Measurement Sphere

Independent of beam geometry and without the need for auxiliary optics, Labsphere’s Laser Power Measurement Spheres are ideal for collecting the total radiant power emitted by highly divergent sources, such as laser diodes as well as a collimated laser beam. Accurate, repeatable measurements may be performed quickly and easily without painstaking positioning and alignment procedures. Integrating sphere measurements of laser power also eliminate polarization effects often associated with filter attenuation techniques.
