Direct full-erect-image Newton binocular reflective telescope

Abstract

The invention discloses a direct full-erect-image Newton binocular reflective telescope which consists of two Newton binocular reflective single-tube telescopes bilaterally arranged in the horizontaldirection in a mirror symmetry way and provided with direct full-erect-image inverting assemblies. Each Newton binocular reflective single-tube telescope consists of a first reflecting mirror, a second reflecting mirror and a third reflecting mirror, wherein the first reflecting mirror is a main mirror, and the second reflecting mirror and the third reflecting mirror form the full-erect-image inverting assembly. The optical axis of the first reflecting mirror is selected as the rotation axis. The single full-erect-image inverting assemblies form visible full-erect real images of a target. Thepaired full-erect-image inverting assemblies rotate around the axes with the single-tube telescopes or independently rotate around the axes, or the positions of the third reflecting mirrors are adjusted in the assemblies, the grouped full-erect real images of the targets are output on the eye lens end horizontal line parallel to the horizontal direction defined by the connecting line of the positions and the central points of the main mirrors of the double-tube system by keeping mirror symmetry operation of the left and right image inverting assemblies, the image surfaces of the grouped full-erect real images are consistent in the horizontal direction, the vertical height difference of the image surfaces is effectively eliminated, the central distance between the image surfaces is adjustable, and the double-eye observing demands of different observers can be met.

Description

technical field [0001] The invention relates to the field of optical binoculars, in particular to a direct-looking full erect image Newtonian reflection binoculars. Background technique [0002] The traditional Newtonian reflecting telescope has always been positioned as a special mirror for astronomical observation and shooting at night, rather than an all-weather multi-purpose mirror that is compatible with the starry sky and ground like the usual refractor, and has dual modes of day and night. and other reasons, the main factors that hinder the traditional Newtonian reflecting telescope from becoming an all-weather multi-purpose mirror like the refractor are the following two aspects: one is the two reflections, one primary mirror and one secondary mirror structure adopted by the traditional Newtonian reflecting telescope , the real image formed is a fully inverted real image, which is far from the fully upright real image necessary for visual observation of the ground; t...

Problems solved by technology

[0004] With the development of refracting binoculars in the direction of large aperture and apochromatism, its manufacturing cost is getting higher and higher, and its own weight is getting bigger and bigger. Compared with the best interchangeable eyepiece refracting binoculars with the best compatibility and relatively higher quality , the caliber increased from 70 mm to 150 mm, the body weight of each binocular increased from about 4 kg to 18 kg, and the market price of each binocular increased from several thousand yuan to about 40,000 yuan; , the large refracting binoculars put forward increasingly stringent requirements for the peripheral equipment such as the pan-tilt bracket that closely cooperates with itself. The support ability and control ability are showing signs of decline, and fans can only turn their attention to large and expensive professional film shooting equipment; in addition to the obvious shortage of weight, price, and availability of peripheral equipment, the factors that restrict the popularity of large refracting binoculars are still Including: use and maintenance restrictions and difficulties in optical axis adjustment. In terms of use and maintenance, the multi-layer lens structure has great difficulties in long-term waterproof, moisture-proof, dew-proof, and mildew-proof; as for optical axis adjustment, the only way is to return to the factory. Small bumps in transportation, shelves, transitions, and use are all defined as unsafe factors; there is no doubt that large-scale refracting binoculars are close to the bottleneck of development in terms of their convenience of operation and economic applicability , there is a growing distance between it and ordinary fans
