Optical involute aspheric surface

摘要

Involute aspheric surface is a new type of optical aspheric surface. In this article, the involute aspheric surface's general equation is discussed, and the characteristics of its aberration and technology are analysed. The conclusion that involute aspheric surface is axial symmertrical rotation aspheric surface, and it has second level aberration and fine characteristics of aberration and technique can be drawn here. Involute aspheric surface has practical value in optical system design, and it can provide a new degree of freedom to the designers of optical system.
