Artifex Engineering designs and manufactures a range of high quality polymer based integrating spheres for the ultra violet, visible and near infra-red. The polymer integrating spheres from are very efficient due to the high reflectivity of the quality material we use. These spheres are CNC machined from solid material – not just coated.The larger spheres have standardized ports for modular configuration. The ports can be populated with either a photodiode or a fibre receptacle. The smaller sized spheres come with an integrated photodiode and an SMA fibre port. These spheres are compatible with out OPM150 series of optical power meters.
We offer a wide range of sizes from small to large; 10mm to 100mm. All sizes can be compatible with our OPM150 series of power meters. Just plug it in to your USB port and start measuring!

Our gold coated spheres are designed for high power applications. We use SMA fibre ports to allow accurate measurement with our OPM series of optical power meters.
High power measurements are often performed using thermopile detectors. Thermopiles however, have the disadvantage of reacting very slowly- typical risetimes lead to measurement periods of 1 second at best. The combination of an ulbricht sphere and a photodiode based power meter allows measuring high power fluctuations on a µs time scale.
The gold integrating spheres are designed for high power applications in the near to mid infrared (NIR and MIR).
These quality spheres provide exceptional power handling capability with liquid cooling available.
