Abstract

Aspheric optical lens surface is getting incorporated more into optical systems for improving different aspects of the system such as resolution, aberration corrections, weight, size etc. However, in comparison to a spherical lens, an aspheric lens poses new challenges in the alignment of the optic as the aspheric geometry consist of a single axis of rotational symmetry in comparison with a sphere which is radially symmetric at any point on the surface. This paper is intended to describe different methods which can be used to specify the centration of an aspheric lens component and how these methods should be chosen according to the intended assembly process.
