19 September 2014 Modeling decenter, wedge, and tilt errors in optical tolerance analysis and simulation
Author Affiliations +
Many optical designs have lenses with circular outer profiles that are mounted in cylindrical barrels. This geometry leads to errors on mounting parameters such as decenter and tilt, and component error like wedge which are best modeled with a cylindrical or spherical coordinate system. In the absence of clocking registration, this class of errors is effectively reduced to an error magnitude with a random clocking azimuth. Optical engineers consequently must fully understand how cylindrical or spherical basis geometry relates to Cartesian representation. Understanding these factors as well as how optical design codes can differ in error application for Monte Carlo simulations produces the most effective statistical simulations for tolerance assignment, analysis, and verification. This paper covers these topics to aid practicing optical engineers and designers.
