G200L – Liquid Cooled, 200mm Gold Integrating Spheres

Liquid cooled gold integrating spheres for high power laser applications in the near to mid infrared (NIR and MIR) with exceptional power handling capability

These liquid cooled gold integrating spheres are designed for high power laser applications in the near to mid infrared (NIR and MIR). They provide exceptional power handling capability.

High power measurements are often performed using thermopile detectors. Thermopiles however, have the disadvantage of reacting very slowly – typical rise times lead to measurement periods of 1 second at best. The combination of an integrating sphere and a photodiode based power meter opens the possibility of measuring high power fluctuations on a µs time scale. This can be useful for setting up and debugging high power CW lasers.

These spheres may be combined with our OPM150 or OPM500 series of power meters via fibre coupling. Just plug it in to your USB port and start measuring!
