The Fine Guidance Sensor (FGS) is part of the instrument module for the James Webb Space Telescope (JWST). The FGS operates at 37 K and provides feedback to correct motion blur caused by relative motion within the observatory - an issue during long exposures. It also provides a tunable camera for science observations. The FGS powered optics comprises three, Three Mirror Assembly (TMA) - style reflective systems - one with finite conjugates and the remaining two are an infinite/finite conjugate pair. This paper addresses the issues of providing traceable interferometric wave-front error measurements when the test optics are in a cryogenic vacuum chamber. To meet space and time limits, we restrict attention to the finite conjugate device for the purposes of this publication.
