Feature

  • 01Abundant glass types

    This catalog covers 18 types of optical glass for use in molded lenses. The glass type designation for these types begins with L-. They are also environmentally friendly, as they do not contain lead or arsenic.

Physical properties

We have prepared drawings and charts that graphically present the refractive index and the Abbe number but also other properties important in the selection of optical glass, including partial dispersion ratio, coloring, specific gravity, temperature coefficient of the refractive index (dn/dT) and the linear expansion coefficient. They are available on the catalog download page.

Product Types

  • Saw cut Centerless Ground Cylindrical Blanks

    These blanks are cut from a precisely ground rod formed on a center less grinding machine.
  • Polished Balls

    These lenses are polished into a spherical shape.
    Polished balls can be used as a preform for glass mold lens.
  • Polished Preforms

    Polished preforms are made from reheated pressings or saw cut ground cylindrical blanks and are used for glass moldings.
    For the dimensions, specifications and other details on the polished preforms, please contact our sales department.
  • Aspherical Glass Mold Lenses

    Aspherical Glass Mold Lenses is the optical products as the following:
    Using the polished glass blanks which was heated up to high temperature and softened, the shapes of high precision aspherical shape mold tool are press-formed.
    For the dimensions, specifications and other details on the lenses, please contact our sales department.
