Abstract

Precision Photonics Corporation (PPC) has developed a method of applying Ion Beam Sputtered (IBS) MWIR antireflective coatings to the interior of a tangent ogive dome. Although IBS has traditionally not been used in this application, it is known that IBS provides the highest density coatings using very hard, durable materials. We achieve a variable coating thickness profile by means of shadow masking coupled with sophisticated 3 dimensional mathematical modeling, which optimizes the antireflection performance over a wide range of look angles for an infrared seeker inside the dome. The coating design for this project survives temperatures up to 1000ºC.
