External stray light from environmental sources degrades image quality in visible and infrared (IR) bands and causes glare, contrast loss, and unwanted reflections. Infrared systems, particularly in the long-wavelength infrared (LWIR) band, also contend with internal stray light from thermal emissions, which can interfere with the intended signal. To address these challenges, we present an optimized baf- fle design for the simultaneous suppression of external and internal stray light in an LWIR catadioptric optical payload—a Cassegrain telescope with a primary mirror, secondary mirror, and field correction lens group. Using a parametric approach, we derived equations to ensure complete blocking of direct in- cidence paths (i.e., direct shots) into the lens group and conducted a parametric search within a stream- lined design space focusing on the lengths and slope angles of the primary and secondary mirror baffles.
This optimized design achieved a 2.7-fold reduction in internal stray light intensity compared to the initial design and decreased the sun avoidance angle from 55° to 10°, as evaluated by the point source transmittance of the sun.
