12 September 2011 A case study for cost-effective lens barrel design
Author Affiliations +
A case study is presented to illustrate some of the performance and cost driving tradeoffs involved in the design and tolerancing of optics and optomechanics, where simple lens barrels are concerned. A double Gauss lens was designed, along with two variations of lens barrel designs for mounting the lenses. The two lens barrel designs are compared, and one is selected for further analysis. Tolerance selection guidelines are given and discussed for the optics, as well as the optomechanics. It is shown how the optomechanical tolerances (axial spacing, element decenter, and element tilt) are derived from their primary parameters for the selected lens barrel design. Finally, Monte Carlo analysis is used, along with the provided tolerancing guidelines, to determine reasonable tolerances in order to satisfy the optical performance and yield requirements.
