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 various telescope technologies at home and abroad, the test methods and test report information of telescopes have been improved.
Accuracy is related to the formulation of standards, preparation of technical documents, compilation of teaching materials and books, design, manufacturing and quality assessment of telescope products.
The uniformity and correctness of the technical language in the text has a significant impact on the development and unified description of the entire sighting telescope product.
In view of the above reasons, according to the technical and usage characteristics of the sighting telescope, the test method and test report information table of the sighting telescope
It is very necessary to standardize and normalize it.
GB/T 45410 "Test methods for optical and photonic telescope systems" is intended to consist of ten parts.
--- Part 1.Basic characteristics. The purpose is to specify the test methods for the technical parameters of telescope systems.
--- Part 2.Binoculars. The purpose is to specify the test methods for the technical parameters of binocular systems.
--- Part 3.Aiming telescope. The purpose is to specify the test methods for the technical parameters of the aiming telescope system.
--- Part 4.Astronomical telescopes. The purpose is to specify the test methods for the technical parameters of astronomical telescope systems.
--- Part 5.Transmittance. The purpose is to specify the test methods for the technical parameters of telescope systems.
--- Part 6.Obscuration glare index. The purpose is to specify the test method for the technical parameters of the telescope system.
--- Part 7.Limiting resolution. The purpose is to specify the test method for the technical parameters of the telescope system.
--- Part 8.Night vision devices. The purpose is to specify the test methods for the technical parameters of night vision device systems.
--- Part 9.Field curvature. The purpose is to specify the test methods for the technical parameters of telescope systems.
--- Part 10.Axial color performance. The purpose is to specify the test method for the technical parameters of telescope systems.

3 Terms and definitions
The terms and definitions defined in GB/T 44403 apply to this document.
4 Experimental method for axial parallax
4.1 General
This test method describes the measurement of the distance between the crosshairs of a collimator and the image plane of the crosshairs of a collimator telescope (hereinafter referred to as the specimen).
The image is formed by the objective lens (the crosshairs are located in the first image plane) or the objective lens and the erect image system (the crosshairs are located in the second image plane) of the specimen.
The distance p'ax between the crosshairs of the specimen and the image plane of the collimator crosshairs along the optical axis is the axial parallax, expressed in diopters (m-1).
Indicated and measured with a visual meter.
