Introduction

Microlens array is an important type of optical element in array optics, in the form of a single lens, two or more lens arrays, wide Widely used in three-dimensional display, coupled optics associated with arrayed optical radiation sources and photodetectors, 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 whose technical content is in line with international standards, which will not only help promote the development of microlens arrays in my country A series of industry norms and orderly development can better promote trade, exchanges and technical cooperation in related fields. GB/T 41869 "Optics and Photonics "Microlens Array" was drafted under this background. The microlens array standard is to be composed of the following 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 is useful for scientific research and industry practitioners to exchange concepts based on a common understanding. --- Part 2.Test methods for wavefront aberrations. The purpose is to clarify the basic characteristics of microlenses by standardizing the test method of wavefront aberration. performance characteristics. --- Part 3.Optical properties test methods. The purpose is to provide suppliers with a test method for determining important indicators of optical characteristics. Provide basis for product delivery. --- Part 4.Geometric properties test methods. The purpose is to provide the supplier with a test method to determine the important indicators of geometric characteristics. Provide basis for product delivery.

1 Scope

This document defines terms and definitions for microlens arrays. This document applies to microlens arrays and their systems within or on the same substrate.

2 Normative references

This document has no normative references.

3 Terms and Definitions

The following terms and definitions apply to this document. ISO and IEC maintain standardized terminology databases at the following addresses. 3.1 Basic definition of microlens and microlens array 3.1.1 microlensmicrolens A lens with an aperture smaller than a millimeter is formed by surface refraction, substrate body refraction, diffraction, or by these combined effects. Note 1.The aperture of the microlens can have various shapes, such as circular, hexagonal or rectangular. The surface of the microlens can be flat, concave, convex or free surface. Note 2.See Appendix A for the characteristics of a single lens. 3.1.2 microlens array microlensarray A collection of microlenses regularly distributed inside or on the same substrate. NOTE 1.Irregular or structured arrays can sometimes be used for beam shaping, spreading and homogenization. Note 2.For the application of the microlens array, see Appendix B ~ Appendix G. 3.2 General features 3.2.1 fE,f When parallel light is incident from the back of the substrate, the distance from the vertex of the microlens to the focal point (the position with the highest optical power density). Note 1.In the case of lens aberrations, the effective front focal length can be different from the paraxial front focal length. Note 2.The effective front focal length is different from the traditional effective focal length because it is measured from the vertex of the lens. ......
