OPTICAL SOLAR TELESCOPE Russian patent published in 2000 - IPC

FIELD: astronomy, applicable for high-precision systematic and photometric and coordinate measurements simultaneously of the entire limb and solar disk diameter, as well as of separate preset regions of solar disks both in the ground and space conditions at continuous observations during a long period of time. SUBSTANCE: the telescope has a casing accommodating a post-focal optical system consisting of the main concave ellipsoid mirror with a central aperture, secondary concave ellipsoid mirror and registering device installed in the telescope focal plane, as well as a plane non-transparent heat-insulating mirror of an elliptic shape with a central aperture and at least with one more aperture, the apertures are located at different distances from the mirror center. The heat-insulating mirror is installed for rotation around the telescope optical axis. EFFECT: simultaneous plotting required for studies of the entire limb and separate preset sections of solar disk. 3 dwg
