Novel high-accuracy low-light level sighting telescope

Abstract

The invention discloses a novel high-accuracy low-light level sighting telescope. A low-light level objective lens of the novel high-accuracy low-light level sighting telescope comprises a single positive lens and two sets of doublet lenses, which can meet the imaging quality requirements of wide beam achromatism and high resolution and ensure that the objective lens is small and light and has good imaging quality; a low-light level eye lens comprises two single lenses and a set of doublet lenses, the structural form is simple and compact, the exit pupil diameter is large and equal to the entrance pupil diameter of a daylight lens, and the imaging quality is excellent. The method of adjusting the space between the single positive lenses and the doublet lenses in the eye lens of the low-light level sighting telescope and the space between the eye lens and the fiber panel of an image intensifier effectively ensures that the systematic optical axis cannot be deviated and the systematic sighting accuracy cannot be changed when the low-light level sighting telescope is used along with the daylight lens. The novel high-accuracy low-light level sighting telescope has a simple structure, and is reasonably designed, and besides high imaging quality, the novel high-accuracy low-light level sighting telescope can be used along with the daylight lens without requiring the daylight lens to be dismounted, still can guarantee the systematic sighting accuracy without being calibrated, and realizes the purpose of rapid day and night high-accuracy observation and sighting.

Description

technical field [0001] The invention belongs to the technical field of optical sights, and in particular relates to a novel high-precision low-light sight. Background technique [0002] The existing sights on the market are generally divided into white light sights and night vision sights. In order to meet the needs of day and night observation and aiming, the method of exchanging white light sights and low-light sights according to different environmental conditions is used to solve this problem. . Affected by factors such as connection accuracy and clamping accuracy, it is necessary to calibrate the sight after changing the sight to meet the requirements of aiming accuracy. The operation steps are cumbersome and the calibration time is long, which does not meet the requirements of high precision and speed. Contents of the invention [0003] In order to solve the above-mentioned defects in the prior art, the purpose of the present invention is to provide a novel high-pre...
