B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers two-channel spectral albedometers «AS-2A» 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 two-channel spectral albedometers «AS-2A» designed to observe diffuse reflection spectra (albedo) and brightness of the earth’s and any other surface.

Albedometer «AS-2A» consists of:
* registration module;
* controlling module;
* receiving module.

Principle of operation:
When measuring the albedo of the earth’s surface the receiving platform of the registration module of channel 1 is located horizontally above the earth’s surface. Photosensors at two surfaces of white scattering platform register the incident and reflected from the surface solar radiation. Surface brightness is registered in channel 2 with a separate photosensor. The measurements are calibrated according to the intensity of the solar radiation scattered by the white platform.

To increase the number of observation points in automatic mode, the registration modules can be combined into a group of up to 3 samples with a single control center. Albedometer has a manual operation mode with single registration module, while the mobility of observations increases.

Specifications:

Observation field	2π steradian
Spectral range, nm	350..900
Spectral smoothing	by choice
Number of observation points in automatic mode	3
Distance between observation points in automatic mode, m	up to 100

Areas of application:
* meteorology;
* industry and energy (monitoring the condition of thermal installations, determining the optimal orientation of solar panels);
* construction (study of the reflectivity of building materials and surfaces, including facades of buildings and other structures);
* satellite systems (formation of a database of reflection spectra from various types of objects on the Earth's surface for calibration of satellite optical instruments).

B.I.Stepanov Institute of Physics offers partners:
* two-channel spectral albedometers «AS-2A» under a manufacturing agreement;
* two-channel spectral albedometers «AS-2A» under a distribution services agreement.
