摘要

We investigated several curved vane baffle designs coated with specular black paint as an inexpensive manufacturingalternative to traditional diffuse baffles vanes to reduce stray light and heat due to absorption in a standard Cassegraintelescope design configuration. The heat absorption is a very large problem in infrared systems and the specular designssolve this part of the problem. Our study involved simulating two different types of baffle systems, diffuse and specularpainted vanes on the main barrel baffle. The first type of baffle consisted of evenly and non-evenly spaced diffuselyblack coated straight planar vanes on the main barrel baffle and a second type using specular black paint on curvedvanes. TracePro, a stray light simulation software from Lambda Research Corporation, was used to simulate andcompare each of the nine baffle systems for stray light rejection. The diffuse black painted straight vane baffle designwas used as the baseline design to compare results to the other eight designs. In all designs except for the baselinedesign, TracePro's local downhill simplex optimization method was used to optimize each vane curvature and spacing inthe main barrel baffle to reject incoming stray light. These curved vanes were designed to reject stray light back out ofthe main barrel baffle rather than to be absorbed by diffuse black paint.
