Wide-angle telescopes for photometry and polarimetry in optical and infrared ranges
Wide-angle telescopes for photometry and polarimetry in optical and infrared ranges

Function

Investigation of the Earth’s atmosphere, comets, interplanetary and interstellar medium with brightness and linear polarization measurements of extended sources and sky background in optical and infrared spectral ranges.

Description

The devices are small diameter telescopes with CCD-detectors for optical and infrared spectral range with spectral and polarization filters. For higher sensitivity, cooling to cryogenic temperatures is possible. Currently produced are: the lab model of cooled 15 cm telescope for IR IKON and GROT sky surveys, monitor of IR background illumination for Altai optic and laser center; polarimeter for night and twilight sky.
