SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units using cryogenic optical calibration sources. To support this work we have used COMSOL Multiphysics® to model the optical coupling of the detectors and to design the optical calibration sources.
