Introduction

Infrared optical chalcogenide glasses are widely used in thermal imaging, infrared sensing, nonlinear devices, phase change storage, photovoltaics and other fields. its products During production, sales and use, performance parameters need to be obtained under standardized measurement methods. It stipulates the measurement of various optical and electrical parameters methods, ensuring the comparability and reproducibility of test results, and establishing the best order for the production, sales and use of infrared optical chalcogenide glass, It is conducive to promoting the mutual benefits of related parties. GB/T 32561 stipulates the measurement methods of various performance parameters of infrared optical chalcogenide glass, It is intended to consist of 5 parts. --- Part 1.Uniformity. The purpose is to describe a test method for the internal homogeneity of external optical chalcogenide glasses. --- Part 2.Streaks. The purpose of this paper is to describe the test method for the internal striae degree of infrared optical chalcogenide glass. --- Part 3.Impurities. The purpose is to describe the test method for internal impurities of infrared optical chalcogenide glasses. --- Part 4.Light absorption coefficient. The purpose is to describe the test method for the light absorption coefficient of infrared optical chalcogenide glass. --- Part 5.Stress birefringence. The purpose is to describe the test method of stress birefringence of infrared optical chalcogenide glass. The five parts of GB/T 32561 respectively correspond to the tests of five important performance parameters of infrared optical chalcogenide glass during use method. This document is the fourth part of GB/T 32561.This document is the qualitative test and On the basis of characterization, the light absorption coefficient of chalcogenide glass products was further quantitatively tested and characterized. Infrared Optical Chalcogenide Glass Test Method Part 4.Optical Absorption Coefficient

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 The transmittance of infrared optical glass in the infrared band. Note. It is characterized by the percentage of light intensity before and after passing through the sample. [Source. GB/T 36403-2018, 2.1, modified] 3.2 The refractive index of infrared materials in the infrared band. [Source. GB/T 34184-2017, 2.1, modified] 3.3 The negative value of the natural logarithm of the internal transmittance per centimeter of light passing through the glass. [Source. GB/T 7962.9-2010, 3.2, modified]

4 Test Principle

When the test light passes through the sample vertically, in addition to the reflection of the sample interface, the light intensity will also be attenuated by the absorption of the sample itself. Passed the test ......
