Optics and photonics. Optical transfer function. Definitions and mathematical relationships Ingestion-build-242630 175 mm nominal diameter1 Scope This International Standard defines terms relating to the optical transfer function and indicates, where pertinent, the mathematical relationships between those terms. It also defines important parameters that should be specified in connection with optical transfer function testing. Table 1 lists the notation and units for the major parameters considered in this International Standard and to be used in ISO 9335 and ISO 9336. The terms and
