Photometer and radiometer

The photometers and radiometers of the frc family enable quick and easy measurement of illuminance and irradiance or luminous intensity and radiant intensity. Combined with the opsira integrating spheres, a simple measurement of the total luminous flux is possible. The unit is traceably calibrated and therefore delivered ready for immediate use. The powerful software also enables automatic measurement of long-term behaviour.

frc'3

The universal Photometer

The photometer frc'3 enables a simple, precise, and absolute light measurement. Designed for the use in harsh surroundings and equipped with high-precision measurement technique, the photometer frc'3 is able to be used easily in laboratories as well as in production lines or during outside service tasks. The photometer frc'3 measures light sources and radiation sources from UV to IR very quickly and efficiently.

The photometer sensor of the frc'3 series can be equipped with a filter changer allowing a radiometrical and a photometrical weighting in one device. Broadband radiometrical filters as well as V(λ) filters or others are possible, up to 5 filter positions are available.

The photometer system frc'3 comes with powerful software supporting the data acquisition and processing.
Measurement data can be processed statistically and edited arbitrarily by a reporter. Printing a test report from the frc software is easily possible, too.
By use of the TCP/IP interface of the frc software the frc'3 sensor can be used in a production line to start or stop measurements, to process measurement data and to control the optional filter changer.

The configuration of the photometer frc'3 is included in goniophotometer robogonio in the alpha product line
