Compact Integrating Sphere Detector
The ISD-10-VL integrating sphere detector employs an 100 mm d/ 4 inch iameter Barium Sulfate (ODP97) coated integrating sphere with 15mm / 0.6 inch diameter measurement port and a photometric detector.
It's photometric detector is equipped with a diffuser so that the detector integrates reflected light from almost the complete integrating sphere surface. This greatly reduces hot spot effects caused by the first reflection of the light signal.
Detector in “Shadow Position”
The detector is positioned close to the measurement port to produce a large acceptance angle within the sphere without direct irradiation of the detector.
Optional Fiber Connector
An optional SMA connector is available to add a spectrometer to the integrating sphere for relative spectral distribution measurement.
Optional Auxiliary Port
In applications where substitution errors by re-reflected light at the measurement port must be compensated an auxiliary port is optionally available.
Traceable Calibrations
Calibration of luminous flux sensitivity in lm is performed at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
