Day-night integral observation sighting telescope

Abstract

The invention belongs the field of optical, mechanical and electronic integration, relates to a sighting telescope for a gun and in particular relates to a day-night integral observation sighting telescope for a gun. The day-night integral observation sighting telescope is characterized in that when the sighting telescope is used at night, and a ray arrives at an eyepiece 8 through an objective lens 1, an image intensifier 9 and a spectroscope 7; a partitioning lens 3 is radiated by a partitioning lighting source 10, and a cross-shaped bright datum line is formed on the eyepiece 8; and when the sighting telescope is used in daytime, a rotary reflector 2 blocks the image intensifier 9, and then the ray enters through the objective lens 1 and then passes through the rotary reflector 2, the partitioning lens 3, a fixed retroreflector 4, a relay lens 5, a fixed retroreflector 6 and the spectroscope 7 so as to arrive at the eyepiece 8, and simultaneously the cross curve of the partitioning lens 3 forms the cross-shaped black datum line on the eyepiece 8. The sighting telescope provided by the invention has the advantages that the white light and shimmer are subjected to light-path confocal imaging by virtue of adjusting the relay lens 5; and the partitioning lens 3 is shared so as to form two cross-shaped datum lines of different colors, thereby achieving a day-night integral observation slighting system.

Description

technical field [0001] The patented technology belongs to the field of optical-mechanical-electrical integration, and relates to a gun scope, in particular to a day-night integrated gun scope with a microscopic night vision function. technical background [0002] Observation sights are mainly used in military, public security, and armed departments, and can be used to observe, capture and aim at targets. Today, the shooting accuracy of firearms is closely related to whether the aiming equipment is advanced. So far, domestic optical sights are single-function daylight sights or low-light sights. They can only be used in a single state during the day or night. When day and night alternate When the scope can only be replaced, this requires two scopes, which brings great inconvenience to the use; secondly, it takes a certain amount of time to replace the scope, and it does not have the ability to respond in real time. A reset error occurs, which affects the aiming accuracy. Th...
