The shrink fitter have been used to fix the optical lenses accurately into the housing by a shrinkage fit. This is a contact problem between the optical lenses and the shrink fitter. The shrink fitter is carefully turned because the form error may affect the alignment of lenses and deformations of those , and spot diameter is also affected. In order to determine tolerance for the shrink fitter, we examined the effect of alignment of lenses and their deformations on optical performance of scanning lenses fixed by the shrink lenses fixed by the shrink fitter theoretically.
