B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers a National etalon for units of spectral brightness, spectral radiance and radiation intensity in the wavelength range from 0.2 to 3.0 µm under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus manufactures a National etalon for units of spectral brightness, spectral radiance and radiation intensity in the wavelength range from 0.2 to 3.0 µm (hereinafter – etalon) is designed to reproduce, store, and transmit the size of the corresponding units to operating etalons and other measuring tools (MT) used for calibration, diagnostics and measurements of optical characteristics of optical radiation sources and receivers.

Etalon includes:
* a complex of measuring instruments for reproducing units of spectral radiance and spectral brightness based on the reference model of a high-temperature blackbody BB3500M;
* measurement system in the ultraviolet region of the spectrum (UV system);
* system for calibration of wide-aperture measuring instruments (View/BIC system);
* environmental monitoring device.

The etalon has the following features:
* the design provides the ability to measure the spectral radiance and radiation intensity at a distance between the receiver and the radiation source of less than 200 mm, which is relevant for measuring the optical characteristics of LEDs and some types of reference lamps;
* the possibility of measuring the spatial distribution of the radiation intensity and spectral radiance of small-sized radiation sources, including LED;
* the thermal stabilization system of the high-temperature blackbody BB3500M model ensures its cooling with an error of 0.2 °C, which allows to improve the metrological characteristics of the etalon and increase its working life.

Economic efficiency of development:
The exploitation of the etalon makes it possible to meet the metrological needs of departments and organizations that use and create spectroradiometric equipment and, thereby, acquires national and social significance.

The metrological characteristics of the National etalon correspond to the world level and allow participation in international comparisons, thereby increasing its competitiveness in the foreign market.

The cost of calibration on the created etalon is much lower than the cost of calibration of one reference lamp on the similar etalon at «VNIIOFI» (Russian Federation), which makes it possible to certify most measuring instruments at significantly lower costs.

The National etalon (NE 51-19) was approved by the resolution of the State Standard № 31 dated 03.06.2019 in accordance with the interstate standard GOST 8.195-2013.
