PANORAMIC TWO-SPECTRAL MIRROR-LENS SYSTEM Russian patent published in 2020 - IPC G02B17/08 G03B37/06 G02B13/06 

FIELD: optics.

SUBSTANCE: mirror-lens system consists of concave and convex mirrors and lens system for transferring image of visual spectrum range. System incorporates a protective glass in the form of a hemisphere, which faces the object with its convexity. Mirrors have internal reflection and solid concave mirror has no mirror coating in central part. Diameters of protective glass and concave mirror are equal, and they are structurally combined into a single hollow sphere. Convex mirror is installed inside hemisphere in central part of protective glass. Protective glass and mirrors with internal reflection are made from the same optical material. Between the concave mirror from the outside and the lens system of transferring the image of the visual range of the spectrum, a spectro-separating mirror is installed and a lens system for transferring the non-visual spectrum image is added.

EFFECT: providing a sealed space between mirrors with internal reflection and dilution of visual and non-visual radiations on different receivers of optical radiation.
