Abstract
Anti-reflection coating of ogive shaped optics presents a number of technical challenges. The principle challenge is obtaining a uniform high transmission coating on a strongly curved surface. The coating must perform well over a wide range of angles. If the optic is exposed to ambient conditions, it must be resistant to rain and dust impact, as well as rapid changes in temperature. The proposed process is a cylindrical magnetron sputtering source to produce a gradient index anti-reflection film. Efforts in Phase 1 will include the demonstration of high performance anti-reflection film on cylindrical and ogive shaped optics in the mid-IR spectral region.
