NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical to ISO 10110-1: 2019 'Optics and photonics - Preparation of drawings for optical elements and systems - Part 1: General' 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 after approval of the Production and General Engineering Division Council.

This standard specifies drawing indication for optical elements and systems. It also specifies the presentation in drawings of the characteristics, including the tolerances of optical elements and systems.

This standard was first published in 1970. This revision supersedes the originally published IS 5920 : 1970 'Recommendations for the preparation of drawings for optical elements and systems'.

This standard has been published in thirteen parts. The other parts in this series are:

Part 2 Surface form tolerances

Part 3 Centring tolerances

Part 4 Surface imperfections

Part 5 Surface texture

Part 6 Surface treatment and coating

Part 7 Non-toleranced data

Part 8 Aspheric surfaces

Part 9 Wavefront deformation tolerance

Part 10 Diffractive surfaces

Part 11 Laser irradiation damage threshold

Part 12 Stress birefringence, bubbles and inclusions, homogeneity, and striae

Part 13 General description of surfaces and components

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.
