The Coronal Diagnostic Spectrometer (CDS) has a pointing requirement of 2 arcseconds, which corresponds to a thermal gradient restriction of 2°C across the optical bench. This paper shows the effect of a transient thermal environment on the pointing performance of the CDS optical bench in terms of thermally induced alignment errors of the optical components. Thermal analysis provides the temperature profiles of the optical bench as a function of various heater scenarios which serve as the load sets for the steady state, non-linear analyses, the results of which are nodal displacements and rotations.
