Overview

Radiometry and Colorimetry Laboratory maintains, improves and disseminates national scales of spectroradiometric and radiometric measurement of optical radiation sources in VUV, UV, VIS and IR range, as well as standards in surface color and appearance in visible light range. We participate in international comparisons to ensure traceability and international equivalence of radiometric and colorimetric standards and measurements. We provide...
