Introduction

Optical thin-film elements are widely used in various fields of science and technology related to optics and photonics to realize reflection, beam splitting, filtering, etc.

Different optical functions such as light are an irreplaceable and important part of the optical system. With the continuous advancement of science and technology, optical thin film components are becoming more and more

It is developing in the direction of higher performance requirements and more diverse demand types. Therefore, it is necessary to formulate a set of technologies specifically for optical thin film technology.

The content is in line with international standards of national standards. This is not only conducive to promoting the normative and orderly development of my country's optical film industry, but also better promoting related

trade, exchanges and technical cooperation in the field. GB/T 26332 "Optics and Photonics Optical Films" was drafted under this background.

determined.

GB/T 26332 adopts the international standard ISO 9211 series and is intended to consist of eight parts.

--- Part 1.Definitions. The purpose is to standardize technical representations of common terms related to optical films.

--- Part 2.Optical properties. The purpose is to standardize the description methods of various spectral properties of optical films.

--- Part 3.Environmental suitability. The purpose is to establish an environmental test method suitable for investigating the environmental adaptability of optical thin film elements.

--- Part 4.Specified test methods. The purpose is to supplement the detailed technical requirements for several environmental test methods, part 3

The test methods are cited in.

--- Part 5.Basic requirements for anti-reflection coatings. The purpose is to establish the basic requirements for commonly used antireflection coatings.

--- Part 6.Basic requirements for reflective films. The purpose is to establish the basic requirements for commonly used metal reflective films.

--- Part 7.Basic requirements for neutral beamsplitters. The purpose is to establish the basic requirements for commonly used neutral beamsplitters.

--- Part 8.Basic requirements for laser optical films. The purpose is to establish the basic requirements for commonly used laser optical films.

The first four parts of the GB/T 26332 series of standards describe general specifications for optical films, and the rest are directed to specific application directions

The optical film specifies the basic technical requirements. GB/T 26332.8 is aimed at laser thin films widely used in laser optical systems.

Optical and Photonics Optical Films

Part 8.Basic requirements for laser optical films

1 Scope

This document specifies the optical properties of films for laser optics, especially the laser power carrying capacity, mechanical properties, chemical resistance and environmental

Basic requirements for adaptability, etc.

This document applies to optical films used in the laser field. This document meets both the requirements of film manufacturers for material selection and preparation methods.

It can also enable users to accurately understand the relevant quantitative regulations of the film product.
