摘要：

A parametric method for the objective measurement of surface damage such as digs and scratches on optical components is described and is intended for use with the new British Standard 4301 (1991). By a comparison of image visibilities of defects with line and spot standards, scratches and digs can be quantified in terms of their line-equivalent widths and spot-equivalent diameters. The codes used on optical drawings are described and guidelines for surface damage thresholds are discussed. The preferred equipment to aid the various stages of inspection and measurement is described and a flow diagram illustrating a typical system for the quality control of transmitting and reflecting components is presented.
