IS 18726 : Part 2 : 2024/ISO 14880-2 : 2006 Optics and Photonics - Microlens Arrays - Part 2 Test Methods for Wavefront Aberrations

ICS 31.260

PGD 39

NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical to ISO 14880-2 : 2006 'Optics and photonics - Microlens arrays - Part 2: Test methods for wave front aberrations' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Optics and Photonics Sectional Committee and approval of the Production and General Engineering Division Council.

The market in microlens arrays is generating an urgent need for agreement on basic terminology and test methods for a definition of the microlens array itself. Standard terminology and a clear definition are needed not only to promote applications but also to encourage scientists and engineers to exchange ideas and new concepts based on common understanding. Considering this the optics and photonics sectional Committee decided to adopt the ISO 14880-1 as an Indian Standard.

Part 1 Vocabulary

Part 3 Test methods for optical properties other than wave front aberrations

Part 4 Test methods for geometrical properties

Part 5 Guidance on testing

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current-practice is to use a point (.) as the decimal marker.
