Integrating Sphere Detector

The ISD-5P-SiUV integrating sphere detector employ a 50 mm diameter ODM98 coated integrating sphere with 10mm diameter measurement port. The unique collar baffle limits direct irradiation of the detector from dispersed light. The collar baffle enables optional detector ports to be added for additional detectors, fiber connectors or auxiliary use. The ISD-5P-SiUV features a UV-enhanced Si photodiode detector for use in the spectral range from 250 to 1100nm spectral range. 

Synthetic Coating 

Gigahertz-Optik’s synthetic ODM98 coating offers almost perfect hemispherical diffuse reflection for best light distribution inside the sphere. 

Traceable Calibrations 

Calibration of spectral radiant power sensitivity in W is performed in 10 nm steps from 250 to 1100 nm at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
