RETROREFLECTOMETER - to measure the 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 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

GL RETROREFLECTOMETER 4.0 SRS Usage
Fast monochromator expands possibilities
The use of a monochromator allows to expand the range of measurement results by a number of parameters determined on the basis of the spectral distribution of reflected light, as well as to analyze changes in the spectral characteristics of reflecting coatings.
