Paper Abstract

A slicer mirror is a complex surface composed by many tilted and decentered mirrors sub-surfaces. The major difficulty to model such a complex surface is the large number of parameters used to define it. The Zemax's multi-configuration mode is usually used to specify each parameters (tilts, curvatures, decenters) for each mirror sub-surface which are then considered independently. Otherwise making use of the User-Defined Surface (UDSDLL) Zemax capability, we are able to consider the set of sub-surfaces as an unique surface. Such a UDS-DLL tools facilitate Integral Field Unit (IFU) designs and make optimization faster by a factor 2-5 compared with the classical multi-configuration mode. Furthermore, analysis and tolerancing can be performed with equal results although some analyses are facilitated in particular those that need to consider several slices such as the cross-talk due to diffraction. In this paper, we present a set of such a UDS-DLL tool to model all types of slicer mirror arrays used in current IFU designs.
