Abstract

A recent survey of the needs of the optical industry concluded that improved specifications and methods of measurement of optical component flaws are an outstanding requirement. After definition of the terms involved, the effect of flaws on the cosmetic quality and function of a variety of different optical systems, together with the benefits likely to be derived from their measurement, are described. Techniques for inspection using probes and area methods employing light scatter are reviewed against the background of existing standards. The case for a new approach to quantify flaws in terms of photometric obscuration, rather than surface area, is presented with a description of a typical instrument able to quantify the amount of light removed from a beam by a flaw compared with a standard flaw which removes all the light. Finally, the present level of international activity concerning standards relating to flaws is discussed with recommendations regarding the future.
