It is widely used in the form of single lens, two or more lens arrays. Widely used in three-dimensional displays, coupling optics related to array optical radiation sources and optical detectors, enhanced liquid crystal displays and optical parallel processor components. With the continuous advancement of science and technology, it is necessary to formulate a set of national standards with technical content in line with international standards, which will not only help promote the development of micro-transmitters in my country, but also The mirror array industry can develop in a standardized and orderly manner, and can better promote trade, exchanges and technical cooperation in related fields. The "Photonics Microlens Array" was drafted and formulated in this context. The microlens array standard is planned to consist of the following four parts. Part 1.Terminology. The purpose is to facilitate the application of microlens array products by defining the basic terms of microlenses and their arrays. It helps researchers and industry practitioners to exchange concepts based on a common understanding. Part 2.Test method for wavefront aberration. The purpose is to clarify the basic Performance characteristics. Part 3.Optical property test methods. The purpose is to improve the quality of optical properties of different suppliers by standardizing the test methods of the main optical property indicators. The compatibility and interchangeability of products from other parties will promote the advancement of microlens array technology. Part 4.Geometric property test methods. The purpose is to standardize the test methods of the main geometric property indicators and standardize the test methods of the different suppliers. To ensure the consistency of supplier product performance and expand its application areas. Optics and Photonics Microlens Arrays Part 3.Optical properties test methods1 ScopeThis document specifies the test principles, test system, test preparation for the optical properties of microlenses in microlens arrays, and describes the test procedures and Test result processing. This document is applicable to the testing of the optical properties of microlenses arrays formed by surface geometric structures and microlenses produced by gradient refractive indices.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.

Microlens. There are three main methods for measuring the focal length of a microlens. measurement based on the microscopic principle (microscopic measurement method), measurement based on the interference principle, and There are two measurement methods. interferometry and confocal imaging. Principles for selecting focal length measurement methods. Microscopic measurement method is suitable for situations where the focal length measurement accuracy requirement is not high and the measurement equipment cost is relatively limited; a) Interferometry is suitable for microlens arrays with large numerical aperture and steep curved edges (usually greater than 30°). Where higher accuracy is required, the method for measuring focal length based on Fizeau interferometer shall comply with the provisions of Appendix A; b) Confocal imaging is suitable for microlenses with small numerical aperture and gentle curved edges (usually less than 30°). The method for measuring focal length should comply with the provisions of Appendix B. c) This document mainly specifies microscopic measurement methods. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41869.3-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 41869.3-2024_English as soon as possible, and keep you informed of the progress.
