Paper Abstract

A short review of the new standards relating to production and testing of optical systems that have been developed recently by the International Organization for Standardization (ISO) is given here. A more detailed account of the current status of the Neutral Optical Data Interface Format (NODIF), the proposed interface between computer- aided-optical-design programs and other computer-aided- design programs is also given. NODIF is one application of the standard for exchange of product model data (STEP) which is a standard for the smooth transfer of data files form one program to another with no loss of information or accuracy. STEP defines a set of protocols for each application, it is device independent and language independent and a reference model for each application is defined and interpreted. A set of conformance classes must be devised, to be used for testing any implementation of STEP in computer software. When implemented, NODIF will enable optical data to be exchanged between different optical or other design programs, or archived electronically, together with all other design data for a complex product. The latest information on the advancement of NODIF and its progress towards becoming an international standard is included.
