DESCRIPTION:
A spherical vacuum reflector contains a reflector body covered with a metalized polymer film, which is attached to the body with a ring that tightens the film thanks to screws and forms a sealed chamber into which fittings with valves and pressure gauges are embedded, through which air is pumped out (or applied), where a vacuum is formed ( vacuum), the degree of which is controlled and provides the metalized film with a spherical concave surface with a certain focus of concentration of rays.
CHARACTERISTICS:
A large-diameter reflector contains a reflector body, a metalized polymer film, a ring that tightens the film thanks to screws, a union with a nipple valve and a pressure gauge, a union with a pressure gauge and a tap, a power steel frame, turntables, bearings, gear motors, switches. The whole structure is mounted on a steel frame support.
ADVANTAGES:
The advantages of this spherical reflector over analogues are the increased geometric accuracy of the surface (sphericity) of the reflector, the quality and accuracy of focusing of its reflecting surface while increasing the efficiency of using the incident radiation, the lightness of the design, and the possibility of manufacturing a large-diameter reflector. When using a large-diameter spherical reflector in optical astronomy, there is a real opportunity to create telescopes with a light mobile main mirror (reflector) up to 100 meters, in contrast to the existing ones with a diameter of up to 10 meters, which will lead to a breakthrough in optical astronomy.
PURPOSE:
The model relates to optical instrumentation, solar technology and lighting engineering and can be used in focusing optical systems in the manufacture of curved reflective surfaces, for example, in the manufacture of optical surfaces of mirrors, adaptive optics elements, telescopes, solar concentrators.
AREA:
The model can be used in focusing optical systems in the manufacture of curved reflective surfaces, for example, in the manufacture of optical surfaces of mirrors, adaptive optics elements, telescopes, helioconcentrators.
TECHNICAL AND ECONOMIC EFFECT:
When using the reflector as a heating device, it is possible to obtain power (in the summer, in mid-latitudes) up to 1 kW / m2, there are 7850 kW from one mirror with a diameter of 100 m. Such a reflector can work with a heat accumulator, a steam generator and an electric generator as part of an electric solar station.
