Control of Linear Astigmatism Aberration in a Perturbed Axially Symmetric Optical System and Tolerancing
Linear astigmatism aberration is undesirable because it rapidly degrades image quality. We discuss some techniques to control and mitigate this aberration, and provide a comparison of lens systems that have been desensitized for linear astigmatism aberration.
