Problems solved by technology

[0002] In modern observation and aiming optical systems, two scopes are generally equipped with white light and night vision scopes. The white light scope is used during the day and the night vision scope is used at night. In addition to the cumbersome calibration and use, it also increases the burden on the user.

Embodiment Construction

[0009] see figure 1 , day and night amphibious observation of the present invention and sighting optical system, are made up of low light objective lens 1, low light tube 2, low light relay image 3, white light objective lens 11, white light relay image 10, combined view prism 8 and eyepiece 6. The white light objective lens 11 is composed of 3 pieces of white light objective lens, and the white light conversion image 10 is composed of 5 groups of 7 pieces of image conversion mirrors; the low light objective lens 1 is composed of 3 groups of 5 pieces of type objective lenses, and the low light conversion Image 3 is composed of 4 groups of 6-piece image transfer mirrors and reflective prism 4. The low-light image and white-light image are imaged on the focal plane of the eyepiece 6 through a cemented prism 8 , reflected by the prism 8 into the eyepiece, and observed by the eye point 7 . The gluing surface of the combined view prism 8 is plated with a semi-transparent and semi...

Abstract

The invention discloses a day and night dual-purpose optical observing and sighting system, which is provided with a daylight system and a low-light level night vision system, wherein the daylight system comprises a low-light level objective lens, a low-light level tube and a low-light level inverter, the low-light level night vision system comprises a daylight objective lens and a daylight inverter, the low-light level inverter and the daylight inverter image a target onto the focal plane of an eye lens by means of a cemented coincidence prism and a day-night changeover switch, a half-transparent, half-reflective film system is plated on the cemented surface of the coincidence prism, and the image of the target is reflected into the eye lens by the coincidence prism, and thereby can be observed by the human eye. Compared with the prior art, the day and night dual-purpose optical observing and sighting system has a simple structure, is reasonably designed, realizes high imaging quality, effectively enhances the human-machine ergonomics of the lens, reduces the carried burden of a user, and effectively meets the requirement of all-weather application.

Description

technical field [0001] The invention belongs to the technical field of sights, and in particular relates to a day and night observation and aiming optical system. Background technique [0002] In modern observation and aiming optical systems, two scopes are generally equipped with white light and night vision scopes. The white light scope is used during the day and the night vision scope is used at night. In addition to cumbersome calibration and use, it also increases the carrying burden of the user. The invention combines the white light mirror and the night vision mirror into one by using a combined view prism, which effectively improves the man-machine function of the mirror and reduces the carrying burden of the user. Contents of the invention [0003] The purpose of the present invention is to provide a day and night dual-purpose observation and aiming optical system that combines the white light mirror and the night vision mirror into one, which effectively improves...
