Light Detectors

Precisely Calibrated For Radiometric, Photometric And Colorimetric Measurement Systems

Gigahertz-Optik Manufactures, Calibrates And Services Light Detectors
Light Detectors, used in combination with Gigahertz-Optik optometers, integrating spheres and components, form complete radiometric, photometric and colorimetric measurement systems.

Typical Light Detector Compositions
A typical detector may consist of a photodiode, optical bandpass filter, diffuser, lens assembly or other optical elements. A complete range of detector housings and configurations designed around the specific application demands of dynamic range, spectral range, physical size and measurement environment are available.

Calibrated & Certified To International Standards
All optical radiation detectors are calibrated and certified by Gigahertz-Optik's calibration laboratory with both absolute sensitivity data and spectral responsivity plot provided.

1. Matching The Light Detector Connector Type To The Appropriate GO Optometer

Gigahertz-Optik light detectors come equipped with a connector type compatible with the particular optometer it will be used with (see table). The (-2) calibration data plug contains an Eeprom that stores the detector's serial number, model, units and calibration data or data table for automatic information transfer to the meter when connected. Both standard BNC (-1) and ITT-9PIN (-4) connectors are straight forward plugs without internal Eeprom.

Connector Type		Optometer
BNC	-1	P-9202, P9801, P-9802, TR-9600
Calibration Data	-2	P-9710, P-2000
ITT (MSDM9)	-4	X9, X1, HCT-99

2. Calculating The Light Dectector's Maximum Measurable Intensity and Resolution

The specifications listed in the following tables include the typical sensitivity factors for each light dectector' calibrated units.The maximum measurable intensity and attainable resolution with the different models of optometer offered can be calculated as follows:

Maximum Resolution = Meter Current Signal Resolution (0.1pA) / Detector Sensitivity Maximum Signal = Max Meter Signal Current (200uA) / Detector Sensitivity
