The straylight rejection of the German Infrared Laboratory (GIRL) baffle system and telescope is investigated. GIRL is being developed to perform experiments in the fields of astronomy and atmospheric physics to wavelengths of 500im. The preliminary design submitted to Ball Aerospace Systems Division (BASD) for evaluation thus reflects some nonconventional attempts to minimize the effects of internal thermal emission and diffraction at these longer wavelengths in addition to suppression of scattered straylight. However, analysis indicates that some of these efforts, namely use of certain low emissivity surfaces, result in higher thermal straylight as well as sacrificing the scattered straylight rejection of the system.
