A major limitation on the performance of lenses is the accuracy with which the elements can be centered. Most methods for alignment of lens elements require rotation of the elements in a precision bearing.Small lenses are difficult to manipulate with precision while mounted in a rotating bearing.A method is described which does not need rotation to center the elements.The advantages and requirements of such systems are analyzed.

This tutorial will explore the process of establishing the specifications for optical components. It is intended to help the Optical Shop Supervisor or Process Engineer gain a better understanding of the reasons behind the specifications sent to the shop by the designers. The factors considered by the Optical Designer and Engineer in selecting materials, finishes, and tolerances, as well as the consequence of excessive variance from specification.
