Summary
A lens manufacturer requires tolerances in the dimensions of a lens to be able to provide a cost estimate and be able to manufacture the lens. Further, for the lens to meet the lens specifications after it is built, it is necessary that the actual lens dimensions do not depart from the nominal design ones by some amounts known as fabrication and assembly tolerances. Thus, the task of the lens designer is not only to provide a lens design that meets image quality requirements, but to also provide tolerances, so that the as-built lens actually meets the specifications and satisfies the needs of the application. Critical goals of the lens tolerancing process are to provide tolerances to each of the constructional parameters of the lens, and to find out the statistics of the as-built lens so that the fabrication yield, and final cost, can be estimated. This chapter provides a primer into the lens tolerancing process. Commercial lens design software allows for the lens tolerancing analyses discussed below.
