Institute for Photometry and Radiometry
Detectors
Inphora's light measuring detectors are built using selected, stability tested, high-grade silicon PIN photocells matched with high quality custom color glass filters to ensure long-life and consistent performance. With our unique scientific backgrounds and our proprietary technology, we are able to provide very high precision matching to target curves provided by the customer.
A Calibration Certificate showing the spectral response and f1' error matching function is provided for the photometric and colorimetric detectors. The f1' value is the most important quality criterion for determining the spectral match to the CIE color matching functions and characterizes the mean deviation of the spectral match weighted with the CIE Standard Illuminant “A” spectral power distribution (see CIE Publ. 53 and 69). Inphora produces photometric and colorimetric detectors with the closest match to the CIE tristimulus functions currently available.
Standard Inphora detector sizes include our DET1 with a 7mm filter, and the DET2 with a 20mm filter, but filter and housing size can be customized to meet your needs. A BNC connector or wire lead may be specified. We have the design and manufacturing capabilities to deliver anywhere from small prototype quantities to high volume manufacturing.
Photometric Detectors
Photometric detectors are available to measure luminous flux using an aperture, or luminous intensity using a diffuser. Inphora photometric detectors conform to CIE specifications and are available in multiple f1’ error classes which are in agreement with the German DIN 5032/Teil 7 classification. Examples include “L” Laboratory grade with f1’<=1.5% and “A” Class A grade with f1’<=3%.

Colorimetric Detectors
Colorimetric detectors use filters designed to obtain CIE tristimulus type responses for colorimetric measurements of objects and light source.
Detector types include X1, X2, Y and Z.

Radiometric Detectors
Radiometric detectors are available to measure radiant flux using an aperture, or radiant intensity using a diffuser. These detectors produce a flat response with maximum deviation of ±10% in the visible (400-750nm) or IR (600-900nm) spectral range.
