SOFIA - Stratospheric Observatory for Infrared Astronomy is a 747sp Boeing aircraft modified to carry a 2.7m telescope. This unique aircraft uses infrared light to study the hidden universe, create a greater understanding of local galaxies and observe the past of our universe. To enhance the effectiveness of the telescope on SOFIA, a baseline of an ideal science instrument needs to be established in a lab setting to help reduce time and make things more efficient when SOFIA is flying. This baseline can be done using the TAAS – Telescope Assembly Alignment Simulator, an instrument that simulates the telescope on SOFIA. In this project, the research team uses the Focus Chop Light Source (FCLS) instrument to mimic a blackbody source on the TAAS. There are 6 different sized aperture holes on the FCLS. These sizes represent different magnitudes of starlight. Optimization of the light path for the TAAS is needed to ensure an ideal baseline.
