Integrating Spheres

The perfect match!

Artifex Engineering manufactures high Quality Gold and polymer integrating spheres for laser applications.

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 µs time scale.

The gold 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 air cooled and liquid cooled versions to choose from.


- SMA fibre ports
- Standard 2 port design (eg: Power and spectrometer). Four ports on request.
- Power density: 5000W/cm²
- Wavelength range: 650nm - 20 µm


Our polymer integrating spheres are machined from solid material - not coated.
The robust devices are perfect for measuring laser power in the visible to NIR.
We offer a wide range of sizes from 10mm to 100mm.
The smaller sizes are compatible with our OPM150 series of power meters.
Just plug it in to your USB port and start measuring!


- Fibre ports: SMA and FC
- Photodiodes: Si, Ge, InGaAs, VIS-enhanced InGaAs, IR-extended InGaAs
- Sphere inner diameters: 10mm, 20mm, 50mm, 100mm
