GL RETROREFLECTOMETER 4.0 SRS
Scanning Retroreflectometer System
Measuring reflective properties and color parameters of the illuminated surface
Measurements in accordance with requirements of international standards
Highest precision and wide measurement range
The realization of standard Illuminant A (2856 K) based on an LED light source* guarantees high luminous output. With a fast monochromator acting as a measuring instrument, spectral measurements improve accuracy of monochromatic radiation measurements, provide access to colorimetric data and allow for recalculation of results to simulate using other types of illuminant.
*Halogen light source available as an option
Full information about the properties of reflected optical radiation
The conventional approach to retroreflectance measurements includes the use of photometers or colorimeters. This limits the amount of information about the assessed radiation in comparison with the output of the GL RETROREFLECTOMETER 4.0 SRS, which allows for complete spectral analysis. Besides the metrics related to the quantity and chromaticity, a large number of quality metrics becomes available.
