timint

Timint is a convention for specifying the optical and geometrical characteristics of optical systems, including lenses, mirror systems, and optical mounts. The term "Timint" is derived from the French phrase "tous ensembles," meaning "all together." This convention is widely used in the field of optics to describe the combined properties of optical systems.

According to the Timint convention, an optical system is described by a set of parameters, including the focal length, field of view, distortion, astigmatism, and chromatic aberration. These parameters are listed in a specific order, beginning with the focal length, followed by the diameter of the lens, the field of view, the distortion, the astigmatism, and finally the chromatic aberration.

The Timint convention has become the standard method for describing the properties of optical systems in a concise and consistent manner. It has been widely adopted in various fields, including astronomy, medicine, and engineering. The Timint parameters are also used to calculate the spot size and the intensity distribution of the light at the exit pupil of the optical system.

In summary, Timint is a set of conventions for specifying the characteristics of optical systems, including lenses, mirror systems, and optical mounts. The Timint parameters provide a standardized way of describing the combined properties of these systems, making it easier to compare and analyze different optical systems.
