Where to Buy Integrating Spheres

Artifex Engineering manufactures high quality polymer and gold integrating spheres for laser applications. These spheres can be combined with our optical power meters to realize high power measurement units. High power measurements are often performed using thermopile detectors. Thermopiles however, have the disadvantage of reacting very slowly – typical risetimes leading 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 microsecond time scale.

Our general purpose integrating sphere systems are designed to spatially integrate radiant flux in order to measure optical radiation. They can be coupled with a sensor to create radiometers, photometers, or spectroradiometers in order to measure the total geometric flux emanating from a light source or the flux density of an illuminated area. Additionally, these sphere systems can be used to measure the output of high power lasers and laser diodes or to measure the reflectance and transmittance of materials.

Gentec Electro-Optics has integrating spheres for laser energy measurements and for power measurements. Instruments for up to 20 mJ energy or 9 W continuous-wave power are available, but also photodiode-based instruments with high sensitivity and speed.
