  • Patent number: 7959286
    Abstract: Solid state lenses, lens blanks, and lens components formed of compressible mixed powders of two or more optical substances where the mixing ratio has been deliberately varied from place to place within the volume of the optical component to produce optically useful variations in the local refractive. The compressible mixed powders are ground as fine powders having mechanical properties that make them capable of being formed into cohesive monolithic masses that are low in scattering. The fine powders may be admixtures of host matrix materials and others which, when combined, provide preferred optical properties such as index and dispersion. Parts possessing transmission from within the range from the ultraviolet to the infrared are possible. The materials are suited to low temperature formation of aspheric lenses transmissive in the near and far IR.

  • Patent number: 7591557
    Abstract: A solid state, compression method for fabricating lenses, lens blanks, and lens components from materials ground into fine powders having mechanical properties the make them capable of being formed into cohesive monolithic masses that are low in scattering. The fine powders may be admixtures of host matrix materials and others which, when combined, provide preferred optical properties such as index and dispersion. Parts possessing transmission from within the range from the ultraviolet to the infrared are possible. The method is particularly suited to low temperature formation of aspheric lenses transmissive in the near and far IR.
