Paper Abstract

The alignment of the JWST NIRSpec spectrograph will use a customised set of optical light sources, imagers and wavefront sensors, which form part of the Optical Ground Support Equipment (OGSE). This has been developed by the Mullard Space Science Laboratory (MSSL) and the Centre for Advanced Instrumentation (CfAI) to be used at the Astrium GmbH, Ottobrunn (Germany) during NIRSpec integration. This paper describes the five precision illumination sources which form a key part of NIRSpec OGSE, and the optomechanical design of the three Shack-Hartmann wavefront sensors used.
