Introduction

The telescope system is the core part of various telescopes and is widely used in astronomical observation, space remote sensing, geodesy, weapons and equipment, With the advancement of science and technology and the development of social economy, the application scope of telescopes is becoming more and more The industry has expanded and product output has gradually increased, and a certain scale has been formed. With the rapid development of various telescope technologies at home and abroad, the telescope is not only an observation tool, but also a A weapon accessory that provides high-precision shooting support at long distances. Its versatility makes it an indispensable accessory in many fields such as military, hunting, and outdoor activities. Therefore, it is necessary to consider the relevant technical parameters of the aiming telescope so that it can play its normal function in various applications. This will ensure the design, quality and application of aiming telescope products, promote coordination among enterprises and improve production efficiency. In view of the above reasons, the main indicators of the sighting telescope are standardized according to the parameters and usage functions of the sighting telescope. And standardization is very necessary. GB/T 45411 "Specification for Optical and Photonics Aiming Telescopes" is intended to consist of two parts. Part 1.General performance instruments. The purpose is to specify the technical parameters and information of general performance collimating telescopes. - Part 2.High-performance instruments. The purpose is to specify the technical parameters and information of high-performance collimating telescopes. - Specification for optics and photonics for sighting telescopes Part 2.High Performance Instruments

1 Scope

This document specifies the classification, interfaces, basic requirements and information provided to users of high performance sighting telescopes. This document applies to high performance scopes for use on handheld firearms and airguns. This document does not apply to ordinary performance sighting telescopes.
