As a result of a 2-year research project, finalised in 2020, GL Optic developed new calibration facilities and created Calibration and Research Laboratory of Optical Radiation ( CARLO ). Today, CARLO is the only laboratory in Central and Eastern Europe equipped with the Black Body Radiator – the primary standard source for implementation of spectral irradiance units. These types of reference standards are found only in the leading National Metrology Institutes (NMIs) in the world, such as NIST, PTB, NPL or VNIIOFI.
The required level of excellence, low uncertainty and traceability of absolute spectral calibration is assured by a double verification of the reference standards. Our high temperature black body radiator was delivered by All-Russian Scientific Research Institute for Optical and Physical Measurements (VNIIOFI).
