The Polymer Integrating Spheres SP50

is designed to enable the monitoring of power fluctuations on a time scale of µs (for comparison thermopiles: 1s at best),  very advantageous e.g. when setting up high power CW lasers. It is also machined from solid material – not coated to  allow perfect measuring of laser power in the visible to NIR. 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!

*The 50mm and 100mm spheres have modular ports with choice of SMA and FC fibre receptacles or photodiode. These spheres may be calibrated upon request.

The high reflectivity and lambertian diffusivity of the polymer we use ensures wide band efficiency over the  full range of 250-2500nm. These 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. The 10mm and 20mm  spheres feature an integrated photodiode (choice of UV-Silicon, VIS-enhanced InGaAs or Germanium) for  optical power measurement, as well as an SMA fibre port for auxiliary functions such as spectral analysis.  Both outputs are located on the back side of the device. Both of these spheres are calibrated and are  compatible with our OPM150 series of optical power meter.
