Knight Optics's Diamond Turned Aspheric Lens for Missile Guidance Systems

02 Apr 2017

Need a little Guidance? Knight Optical can supply you with a custom made Diamond turned aspheric lenses for use within Missile Guidance Systems.

Diamond turned aspheric lenses are typically used in optical assemblies such as missile guidance systems, and other military based instruments.

Knight Optical offers diamond turned aspherics from a range of infrared materials including Germanium (Ge), Calcium Fluoride (CaF?), Zinc Sulphide (ZnS), Zinc Selenide (ZnSe), Aluminium (Al) and chalcogenide glasses like AMTIR (Ge₃₃As₁₂Se₅₅).

Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays, potentially replacing a multi-lens system. This in turn provides the camera system with a better image quality.

Typical specs:
Material: Germanium, ZnSe, Caf2, Silicon, Zinc Selenide (For LWIR)
Diameter: Up to 200mm dia +0, -0.02mm
Thickness: +/- 0.2mm
Flatness: < 1/2 wave over 90% aperture
Surface Quality: < 40-20 scratch/dig
Parallelism: 5 arcmin
Coating: AR/DLC (3-5 micron, 7-14 micron, 10-12 micron)

Our Aspheric lenses are checked for quality in our state-of-the-art Metrology laboratory using equipment from Trioptics, Varian and Starret allowing us to work to the highest QA standards and meet the tolerance specifications on these precision components.
