B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers an automated container-type multi-wavelength polarization Raman lidar «POLYUS» for atmospheric sensing 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 automated container-type multi-wavelength polarization Raman lidars «POLYUS», designed for measuring the height profiles of optical properties of aerosol and clouds in the spectral range of 355..1064 nm, concentrations of aerosol fractions and identification of the phase composition of clouds.

The «POLYUS» lidar measures back-scattering signals at 355, 532 and 1064 nm wavelengths, as well as the depolarized component of the lidar signal at 532 nm in day and night time. In night time the lidar provides measurements of in day and night time. In night time the lidar provides measurements of Raman scattering signals with atmospheric nitrogen at the wavelengths of 387 and 607 nm. Atmospheric probing is carried out at the distance of up to 15 km along vertical and inclined routes.

Lidar consists of the following main functional blocks:
* emitter – diode-pumped YAG laser;
* small receiving lens of the near-field registration system;
* large receiving lens of the far-field registration system;
* receiving unit of the of the near-field registration system;
* receiving unit of the far-field registration system;
* power supply of the laser;
* thermal control system;
* control PC.
