Drawing Standards
Two commonly used standards – International Standards Organization (ISO) – American National Standards Institute (ANSI) z
American Society of Mechanical Engineers (ASME) is now responsible for updating & maintaining these standards
These standards explain how to indicate/callout the desired features on a drawing for a finished product The values of these desired features are not specified by these standards ISO standards are fairly commonly used in optical industry and shops 2/20/2006
Page 2
Optical Drawing Standards
The two standards that are of greatest interest are: – ISO 10110-X-1996 (E) - Optics and optical Instruments - Preparation of optical drawings for optical elements and systems – ISO 9211 - Optical coatings
ISO 10110 is similar to ASME Y14.18M. There is no American standard equivalent to ISO 9211 ISO 10110 has 13 parts:
– Part 1 z
General
Covers the mechanical aspects of optical drawings that are specific to optics and not already covered in one of the other ISO drawing standards. 2/20/2006
Page 3
ISO 10110 Standard
Part 2 Part 3 Part 4
Material Imperfections - Stress birefringence Material Imperfections - Bubbles and Inclusions Material Imperfections - Inhomogeneity and striae
– Parts 2-4 cover material related parameters controlling the quality of glass
Part 5
Surface form tolerances
– Concerns figure measurement and differentiates between figure measured visually with a test plate or with a phase measuring interferometer
Part 6
Centering tolerances
– Deals with centering errors and allows either an entirely mechanical method of tolerancing or an optomechanical one.
2/20/2006
Page 4
ISO 10110 Standard
Part 7
Surface imperfection tolerances
– This is equivalent to scratch and dig or surface beauty specification
Part 8
Surface texture
– Concerns ground and . polished surface texture and is unique to this standard
Part 9
Surface treatment and coating
– Tells how to indicate that a surface will be coated, but not what the specifications of the coating are which is covered in ISO 9211.
Part 10 10
Table representing data of a lens element
– Tells how to describe the parameters of an optical element in tabular form – It is the foundation of the effort to simplify transfer of data about optical elements electronically 2/20/2006
Page 5
ISO 10110 Standard
Part 11
Non- toleranced data
– Table of default tolerances on optical parameters – If a particular parameter is not specified, it should then be made to the tolerances given in this table
Part 12
Aspheric surfaces
– Defines how to describe an aspheric surface. – This method method has been coordinate coordinated d with the major major vendors of lens lens design software so the definitions are consistent
Part 13 13
Laser irradiation damage threshold
– Tells how to specify a laser power damage threshold on an optical component

Advantages of ISO Standards
Offer guidance on suggested values of certain features Contain a listing of default tolerances t olerances Much more thorough in their treatment of drawing features Being integrated in optical design software Drawings created using ISO standards are virtually noteless Indications on drawings use alphanumeric symbols Drawing can be interpreted by persons having any language background background without having to translate it
