Recommendations for specifying the optical performance of lenses for television cameras

PUBLISH DATE 1972
BSI BS 4793:1972

These recommendations are for the specification and assessment of the optical performance of lenses for use with television cameras. These may be either zoom lenses, variable focal length lenses, or single focal length lenses, and they may be required to operate in either black-and-white or colour reproduction systems.

A special feature of these recommendations is that they adopt the optical transfer function (OTF), or more specifically its modulus, the modulation transfer function (MTF), as a method of assessing and specifying image quality.

These recommendations cover the performance of the lens as a complete optical unit but do not deal with the performance of individual component parts. The condition of test must however include any additional glass paths between the lens and the image plane that are required by the optical design, such as may be introduced by colour filters, beam splitting blocks, the face plate of the camera tube, etc.
