Integrating Sphere Power Detectors

Integrating sphere power detectors enable the particularly uniform and precise measurement of laser power. They operate on the principle of diffuse reflection: the incident laser light enters a hollow mirrored sphere through a small opening, where it is scattered multiple times and hits the sensor inside in a uniformly distributed manner. This effectively attenuates high power and compensates for local intensity fluctuations, enabling you to achieve reliable measurement results even at high power. These detectors are ideal for use with continuous wave lasers and pulsed lasers with high repetition rates starting at 10 kHz.

Detectors with integrating spheres offer a response time of only 0.2 seconds and operate with low intrinsic noise and a high dynamic range. The durable inner coating of the integrating sphere ensures a long lifetime and stable measurement results. The detectors are only suitable for low divergences, such as collimated or focused beams. Upon request, the specifications can be adapted to your requirements at any time.
