a sight glass

Abstract

The invention provides a spotting scope which is characterized by comprising a scope body, a reticle and an optical zooming system, wherein a light incidence end and a light emission end are arranged on the scope body. The optical zooming system comprises an objective lens group, a first lens group, a second lens group and an eye lens group, wherein the objective lens group is arranged at the incidence end of the scope body, the eye lens group is arranged at the emission end of the scope body, the first lens group and the second lens group are arranged in the scope body, and the objective lens group, the first lens group, the second lens group and the eye lens group are arranged from object space to image space in sequence. Focal lengths f1 of the first lens group and focal lengths f2 of the second lens group meet the following relational expression: 1<f1 / f2<1.6. The reticle is arranged between the objective lens group and the first lens group and perpendicular to the objective lens group and the first lens group, and partition grooves are formed in the reticle. The spotting scope has a distance measurement function, accessories can be arranged on the spotting scope, and light reflection of the objective lens group is avoided.

Description

technical field [0001] The invention relates to the field of optical instruments, in particular to a target sighting mirror. Background technique [0002] The target scope is an optical instrument for remote observation, which is widely used in the environment and military fields. Especially in the military field, although the scope weapon used by the observer can achieve high-magnification observation and aiming at the target, it can assist the sniper to check and correct the trajectory of the gun, but the scope lacks a reticle with a scale, so The distance to the target cannot be measured. Especially in the case of long-distance aiming at the target, the inability to measure the distance of the target will cause a great deviation in the aiming accuracy. [0003] In the field of observation devices, the demand for accessories is increasing. So far, hundreds of new accessories have been invented to be mounted on weapons through tactical rails, such as red dot reflex sights...

AI Technical Summary

Problems solved by technology

However, the target sight glass in the prior art cannot be equipped with accessories, and its practicality is very limited.

[0004] At the same time, the reflected light from the objective lens of the target sight may expose the position of the observer

In the military field, once the ambush position is exposed on a complex battlefield, it means the failure of the tactical mission, and even endangers the lives of soldiers in serious cases.

Even if it is used in civilian fields, such as bird watching activities, the light reflected by the objective lens may drive away birds or cause nuisance to other people
