Description

(5) DOME OPTICAL SYSTEMS

I

The invention relates to buildings, for example, for aerodynamic equipment and can be used in those cases, when in the closed position the dome must protect the equipment from atmospheric influences and significant dynamic loads (hurricane, shock wave), and in the open position allows The astronomical equipment does not have a circular view of the elevation angle allowed by the viewing window of the dome.

A rotating dome is known, comprising a support part, an actuator, a double-winged visor overlapping the viewing slot, the flaps of which are hingedly mounted on both sides of the dome l.

The disadvantages of this dome are the increased drive power of the dome rotation, since the visor leaves are mounted on a rotating dome, while increasing its weight and the need to have additional devices to service the outer surface of the dome.

The closest technical solution to the proposed is a rotating dome of optical systems, such as astronomical telescopes, including a rotating spherical shell with a support ring, a fixed base, a drive and a visor,

10 provided with a scaffolding, which is hingedly mounted on an axis passing through the center of the spherical shell and fixed on the fixed base 2.,

15

The disadvantage of this dome is the limitation in the elevation angle of the viewing zone of the optical system, since the axis of rotation of the visor coincides with the center of the spherical shell.

20

The purpose of the invention is to expand the viewing area of the optical system.

Claims (2)

This goal is achieved by the fact that in a dome of optical systems, mainly astronomical telescopes, including a rotating spherical shell with a viewing (with a window and a support ring, a fixed base, an actuator and a collector mounted on an axis, and mounted on a fixed base, The axis of rotation of the visor is located below the center of the hemispherical shell, and the lower edge of the viewing window is located at a distance, not less than the radius of its pupil, from the center of the optical system. system The dome consists of a hemispherical shell 1, rigidly connected to a support, a ring 2, supported on rubberized wheels 3. On both sides of the fixed base 4 of the dome, hinged on a common axis 5i located below the center 6 of the hemispherical shell, the visor 7, which overlaps the viewing window 8 and is kinematically connected with the drives 9. In order to reduce the drive power of the movement of the visor, the sash is equipped with a counterweight (not shown in the drawing). The support ring 2 is provided with a pin 10, kinematically connected with the rotational drive drum 11. To prevent the dome from moving away from wind loads and to ensure correct engagement of the spun-screw gear, the search rollers are installed in the drawing (not shown). 9 The normal operation of the optical instrument is ensured by moving to the field of view in elevation and rotating the dome in synchronization with the optical system of the telescope. In comparison with the known, the proposed Cugol optical systems increases by 20% the field of view of the optical system in elevation. The invention The dome of optical systems, mainly astronomical telescopes, comprising a rotating hemispherical shell with a viewing window and a support ring, a fixed base, an actuator and a visor with scaffolds pivotally mounted on an axis and fixed on a fixed base, characterized in that for the purpose of expansion optics of the optical system, the axis of rotation of the visor is located below the center of the hemispherical shell, and the lower edge of the viewing window is located from the center of the optical system at a distance not less than the radius of her pupil.
