An integrating sphere detector is composed of two elements. First, light enters a hollow sphere through a small aperture and it diffuses inside the sphere with multiple reflections on the sphere's inner coating. Second, a small uniformly-lit aperture at another position in the sphere samples a portion of this diffused light and sends it onto a sensor. 

Basically, integrating spheres act as attenuators to allow for the use of smaller and faster detectors. Integrating sphere power detectors offer many advantages: fast response, high sensitivity, excellent spatial uniformity.

We currently offer two models of integrating sphere power detectors but, as with all our other product lines, we are always ready to work with you on the design of a custom product that will perfectly suit your measurement needs.
