--- ISO 10109-4 (see Chapter 4) is replaced by the normative reference ISO 20711 to conform to the Chinese standard usage habits;

--- Changed the content of "Basic Requirements" (see Chapter 4) to conform to the usage habits of Chinese standards;

--- The normative reference GB/T 45410.1 replaces ISO 14490-1 (see Chapter 4) to conform to the standard usage habits of my country;

--- The normative reference GB/T 45410.2 replaces ISO 14490-2 (see Chapter 4) to conform to the standard usage habits of my country;

--- The unit m/km (see Table 4) has been deleted to conform to the usage habits of Chinese standards.

The following editorial changes were made to this document.

--- Added unit items in Table 1 and Table 2;

--- The informative reference GB/T 45412.2 replaces ISO 14133-2.

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, culture and education, etc.

Sports, culture, entertainment, tourism and other fields. With the advancement of science and technology and the development of social economy, the application scope of telescopes is expanding.

The industry has taken shape as the output of products has gradually increased.

With the rapid development of binoculars technology at home and abroad, binoculars are not only an observation instrument, but also a portable with its high-definition, versatility and high definition, it has become an indispensable tool for outdoor activities, sports events, astronomical observation and security monitoring.

Therefore, the relevant technical parameters of binoculars enable them to function normally in various applications, thus ensuring the production of binoculars.

Improve product design, quality and application, promote coordination among enterprises and improve production efficiency.

In view of the above reasons, according to the parameters and usage functions of binoculars, it is necessary to analyze the main indicators of binoculars.

Standardization and normalization.

GB/T 45412 Specification for binoculars, telescopes and telescopes for optics and photonics contains the terminology and it contains clauses such as definition, basic requirements and information to be provided to users, and specifies binoculars according to different parameters and various characteristics.

GB/T 45412 "Optical and photonic binoculars, telescopes and observation mirrors Specification" is intended to be divided into two parts.

--- Part 1: Common performance instruments. The purpose is to specify the technical parameters of common performance binoculars, telescopes and observation mirrors.

Numbers and information.

--- Part 2: High-performance instruments. The purpose is to specify the technical parameters and information.

3 Terms and definitions

The terms and definitions defined in GB/T 44403 apply to this document.

4 Basic Requirements

According to the allowable deviation of optical characteristics (see Table 1) and the minimum requirements of optical characteristics (see Table 2), binoculars, monoculars and Basic requirements for observation mirrors.

Tolerance is the maximum allowable deviation between a measured value and the nominal value, where the nominal value is determined by the manufacturer or distributor.

All deviations and parameter values refer to the values measured on the optical axis.

The environmental requirements for binoculars, telescopes and spotting scopes should comply with ISO 20711.

Tables 1 and 2 specify the requirements for various characteristics, which should be in accordance with GB/T 45410.1, GB/T 45410.2 and ISO 14490-7.
