NATIONAL FOREWORD

This Indian Standard (Part 11) which is identical to ISO 10110-17 : 2004 'Optics and photonics - Preparation of drawings for optical elements and systems - Part 17: Laser Irradiation Damage Threshold ' 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.

This standard specifies the presentation of design and functional requirements for optical elements in technical drawings used for manufacturing and inspection. It also specifies rules for the indication of the damage threshold from laser irradiation up to which optical surfaces shall not exhibit any damage as defined in ISO 11254-1.

IS 5920 (Part 1) supersedes the first published Indian Standard IS 5920 : 1970 'Recommendation for the preparation of drawing for optical elements and system'.

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

Part 1 General

Part 2 Surface form tolerances

Part 3 Centering tolerances

Part 4 Surface imperfections

Part 5 Surface texture

Part 6 Surface treatment and coating

Part 7 Non-tolerance data

Part 8 Aspheric surfaces

Part 9 Wave front deformation tolerance

Part 10 Diffractive surfaces

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.
