SPACE-BASED SOLAR OPTICAL TELESCOPE (VERSIONS) Russian patent published in 2017 - IPC G02B23/06 G02B17/02 

FIELD: measuring equipment.

SUBSTANCE: invention can be used for measuring parameters of active areas of the solar photosphere and chromosphere with a high angular resolution in the conditions of the near and the far space. Solar optical telescope includes a primary concave mirror and a field mirror installed in its focus able to turn a light beam reflected from it. Primary concave mirror is made with the minimum thickness from a quartz glass, on the working surface of which a dielectric coating is applied reflecting the solar radiation in a given spectral wavelength range and transmitting the radiation not used for the analysis. Dimensions of the inclined field mirror confine the image area in the square size of the investigated section of the solar surface. In the first version the field mirror reflects a light beam onto the secondary mirror reflecting the light beam onto arranged in series a rotary mirror and a collimator. In the second version – onto a lens transmitting the light beam onto arranged in series a rotary mirror and a collimator.

EFFECT: providing high spatial resolution, effective protection against thermo-optic effects and the minimum weight.
