Paper Abstract

A midwave infrared (IR) imager with silicon lenses and a laminated plastic surface has been made. It has a focal length of 50 mm and f/# of 2.6. Typically this type of lens system would be made out of silicon, germanium, or some other materials transparent in the midwave infrared regime. The design of the lens system would include aspheric and/or diffractive surfaces that require the use of a single point diamond turning machine to make it. In this system aspheric/diffractive silicon lenses have been replaced with a flat piece of silicon coated with a thin layer of plastic that has an aspheric/diffractive surface.
