The high reflectivity and lambertian diffusivity of the coating we use ensures wide band efficiency over the full range of 650nm-20µm.
These gold integrating spheres can be used for optical power measurement as well as beam homogenization for accurate spectral analysis.
The 100mm sphere exhibits a homogeneity of better than 1% at the 25mm port when illuminated through the side (fibre) ports.
We offer both convection cooled and liquid cooled models, depending on the power handling required. The convection cooled models feature a lapped, coated back plate suitable for mounting to a forced air or liquid cooled cold plate for higher power handling.
The 25mm spheres have modular ports with choice of SMA and FC fibre receptacles or photodiode (choice of Germanium, VIS-enhanced InGaAs and IR-extended InGaAs).
The 65mm and 100mm spheres have a choice of SMA or FC fibre ports. Photodiode ports are not offered since these spheres are designed for high power measurement whereby the sphere itself will become warm. This would change the sensitivity of a mounted photodiode.
These gold integrating spheres may be calibrated upon request. The photodiode port may be terminated with a BNC or SMA receptacle or with our OPM150 connector. Using the OPM150 connector, the integrating sphere is compatible with our OPM150 series of optical power meter.
Accessoires
Our adapters use our proprietary design to eliminate back reflections into the detector which would otherwise result in miscalibration of the detector.
They may be fitted by hand, or more conveniently by using the adapter mounting tool (order code 20.430.00018).
