Abstract

FIELD: optical instrumentation; used in the development of optical sights for sporting and hunting weapons. The purpose of the invention is to increase the luminosity and decrease the length. Lens 1 of a double convex lens, glued together from a positive 4 and negative 5 lenses, and a positive meniscus 6 builds a real inverted: an image of the object. The wrapping system 2, containing component 7 from negative meniscus 9 and double convex lens 10 and component 8 in the form of glued positive 11 and negative 12 lenses, reverses the image of the object once more and builds a direct enlarged real image. This image is viewed through the eye of the eye 3, in which the first component is glued twisted 13 and twofold 14 lenses, the second component twofold lens 15 and the third glued double tip 16 and twisted 17 lenses. The length of the system is 199.5 mm, the relative aperture of the lens is 1: 2, the angle of the field of view 8, the exit pupil diameter is 6 mm. 1 il. (L

The invention relates to optical instrumentation, namely, telescopes intended for observing distant and dimly lit objects.

The purpose of the invention is to increase the luminosity and decrease the length.

The drawing shows the optical layout of the telescope.

The telescope contains a lens 1, a wrapping system 2 and an ocular p 3.

The lens has a rendered entrance pupil and consists of a dual-sided lens containing lenses 4 and 5 with optical powers of different signs, and a positive meniscus 6, with the convex side facing the plane of objects. Lenses 4 and 6–20 are made of glass with a refractive index of 7476 and a dispersion coefficient of g 50.21,

The reversing system 2 consists of two components 7 and 8, Component 7 25 is made of a negative meniscus 9, the concave side facing the lens 1, with a glass refractive index, 4891, and a coefficient of dislocation of the lens 1: 2, angle of view of the telescope 8 ° length systems 199.5 mm, exit pupil diameter 6 mm,

With such external characteristics, spherical aberration for the main wavelength is not more than 2, spherochromatism is not more than 5; astigmatism not more than 3 diopters, relative dispersion of 2%, increase chromatism not more than
