Ophir’s proprietary coating control results in superior thickness uniformity of dome coatings. This results in improved image quality in any viewing angle. The systems’ superior optical performance provides improved target acquisition in any direction.
High numerical aperture systems, as found in IR guided missiles, typically require numerous elements, some of which have steep convex or concave spherical surfaces (domes). These must be properly designed to meet both the extreme operational requirements and accurate target acquisition.
The system’s operating waveband and non-uniformity correction affects the sensitivity of infrared imaging detecting systems. For sharply curved spherical components, such as domes, controlling the coating thickness uniformity is crucial. If not properly corrected, the non-uniform thickness profiles will severely affect the image quality and the coating durability.
Ophir developed a unique rotating coating system to solve the non-uniformity problem. Coupled with thorough testing techniques, we are able to achieve superior thickness uniformity control for dome coatings. This results in improved image quality from the optical system, in any viewing angle and maintains the systems’ optical performance, providing target acquisition in any direction.
