It also incorporates the Technical Corrigenda ISO 14880-1:2001/Cor 1:2003 and ISO 14880-1:2001/Cor 2:2005.ISO 14880 consists of the following parts, under the general title Optics and photonics Microlens arrays: Part 1: Vocabulary

35、s part of ISO 14880 is to clarify the terms used in the field of microlens arrays.Microoptics and microlens arrays are found in many modern optical devices.1They are used as coupling optics for detector arrays, the digital camera being an example of a mass market application. They are used to enhanc
36、e the optical performance of liquid crystal displays to couple arrays of light sources and to direct illumination for example in 2D and 3D television, mobile phone and portable computer displays. Microlens arrays are used in wavefront sensors for optical metrology and astronomy, lightfield sensors f
37、or threedimensional photography and microscopy and in optical parallel processor elements.Multiple arrays of microlenses can be assembled to form optical systems such as optical condensers, controlled diffusers and superlenses.23Furthermore, arrays of microoptical elements such as micro-prisms and m
38、icro-mirrors are used.45The expanded market in microlens arrays has generated a need to agree on basic terms and definitions for microlens arrays and systems and this part of ISO 14880 aims to satisfy that need.5 DIN EN ISO 14880-1:2016-12 EN ISO 14880-1:2016 (E) 1 ScopeThis part of ISO 14880 define
39、s terms for microlens arrays. It applies to microlens arrays which consist of arrays of very small lenses formed inside or on one or more surfaces of a common substrate and systems. The aim of this part of ISO 14880 is to improve the compatibility and interchangeability of lens arrays from different
40、 suppliers and to enhance the development of technology using microlens arrays.2 Terms and definitions2.1 Basic definition of microlens and microlens array2.1.1microlenslens in an array with an aperture of less than a few millimetres including lenses which work by refraction at the surface, refracti

The surface of the lens can be flat, convex or concave.2.1.2microlens arrayregular arrangement of microlenses on
