Paper Abstract

The change of the angle characteristic of an optical system when a component parameter is varied follows from first order perturbation theory. Simple formulas are obtained for the sensitivity of the angle characteristic to changes in position, form and refractive index. These formulas can be applied in the design and assembling of optical systems. In assembling we use them for the measurement of decenters; in design we can obtain the mechanical tolerances from them, and also the magnitude of steps in parameter space to be taken in an optimization procedure. We apply our analysis to the systems that were discussed in a previous paperl. It will be seen that the concept of strain discussed in that paper also applies to the calculation of tolerances. The sensitivity of a system to component shifts and tilts correlates with the strain caused by this component. The sensitivity analysis developed in this paper therefore confirms the conclusion of the previous paper. 1 J.L.F. de Meijere, J.A. Schuurman and C.H.F.
