This standard is sometimes referred to as the “Scratch and Dig Standard.” It establishes uniform practices for stating, interpreting, and inspecting surface imperfections of many different types – scratches, digs, chips, fractures, and others – for transmissive and reflective optical elements and assemblies. This standard provides two alternative notations for specifying surface imperfections. A numerical…
This standard is sometimes referred to as the “Scratch and Dig Standard.” It establishes uniform practices for stating, interpreting, and inspecting surface imperfections of many different types – scratches, digs, chips, fractures, and others – for transmissive and reflective optical elements and assemblies. This standard provides two alternative notations for specifying surface imperfections. A numerical notation indicates the allowable visibility of surface imperfections under specific viewing conditions. An alphabetic notation indicates the allowable size of surface imperfections. It is the responsibility of the optical engineer to choose which notation to use. This standard does not address the impact of imperfections on element or system performance.
This Standard divides the infrared region of the electromagnetic spectrum from 0.750 microns to 30.0 microns into named subregions, also known as bands, on the basis of the kinds of detectors or materials used to sense infrared radiation. It defines the generic form of the Abbe dispersion formula for materials that operate in the infrared…
This Standard divides the infrared region of the electromagnetic spectrum from 0.750 microns to 30.0 microns into named subregions, also known as bands, on the basis of the kinds of detectors or materials used to sense infrared radiation. It defines the generic form of the Abbe dispersion formula for materials that operate in the infrared spectrum and specifies reference wavelengths for standard Abbe numbers in each of the named bands. This Standard also defines standard reference wavelengths for the general metrology of infrared materials and components in each of the spectral bands.
