Abstract
An optical component, for example a lens, integrally formed of a nano/nano class nanocomposite optical ceramic (NNCOC) material. The constituent nanograin materials of the NNCOC material are selected to tailor the thermal and optical properties of the lens so as to provide a lens with a substantially constant focal length over an operating temperature range and/or an optical system in which the image position does not change appreciably over the operating temperature range.
