Tolerancing is the analysis of the sensitivity of a system to the perturbations introduced through manufacture, assembly and test errors. OpticStudio supports a comprehensive, flexible, and powerful integrated tolerance analysis capability. Tolerances are set using a Tolerance Wizard and a combination of user selectable options. Default tolerances include ranges on radius, fringes, thickness, position, x and y tilt, x and y decenter, irregularity, wedge, glass index, Abbe number, and more. OpticStudio lets you analyze the effects of these tolerances, and to provide adjustments and assembly procedures to simulate the complete manufacture, test and assembly process.
