Paper Abstract

There is a growing need for lenses capable of determining the precise object distance and field of view (FOV) which needs to be met with a high degree of accuracy and repeatability. Difficulties achieving this accuracy arise with zoom lenses due to the dependence of field of view on the focus position. The depth of field phenomenon is also an issue which must be addressed. In addition, the accurate measurement of element positions can also be an issue. In this paper, we will explore these challenges and offer a solution in the form of metric zoom capability.
