  • Mechanism to mold glass lenses using an implanted precision glass molding tool
    Publication number: 20050126226
    Abstract: A method for fabricating a molding tool for mold glass optical elements therewith is taught. The method comprises the steps of figuring the molding tool to have a predetermined mold surface; applying an attenuating coating to the predetermined mold surface; implanting metal ions through the attenuating coating and into the predetermined mold surface; and removing the attenuating coating leaving the predetermined mold surface with metal ions implanted therein. The method of fabrication allows for the molding tool made therewith to be used for molding optical elements from eco-glasses such as titania at high temperatures without generating adverse surface chemistry effects in the molded element.

  • Composite optical interference filter for use in film scanner system
    Patent number: 5099359
    Abstract: A composite optical interference filter is used in a film scanning system having a high speed CCD imager. Multiple, alternating, variable thickness layers of higher and lower index thin film oxides deposited on an optically transmissive substrate constitute the filter and enable the filter to provide color balance, notch rejection, and IR rejection all in the same device. Three such filters in a lamphouse of the film scanning system can be selected to match the system spectral response of the CCD imager and the film thereby providing equal density and color balance of the images on the film.

  • Telecine scanning apparatus with spectrally-shifted sensitivities responsive to negative or print film dyes
    Patent number: 5003379
    Abstract: A telecine scanner is selectively conformed to evaluate the dye densities characteristic of either negative or print film. The film is interposed in a light path between a light source and a pickup stage that develops a plurality of color output signals from the light passing through the film. Color channel filters included in the pickup stage have spectral passbands in the respective colors that are broad enough to include the spectral dye densities of both negative and print materials. The scanner sensitivity is further limited to a particular film material by inserting an appropriate shaping filter set into the light path, preferably between the light source and the film, for conforming the peak sensitivity of at least one of the passbands to the peak spectral density of the corresponding dye of the particular film material.

  • Beam splitter for color imaging apparatus
    Patent number: 5002365
    Abstract: A beam splitter for color imaging apparatus is disclosed. The beam splitter comprises two prism elements which are joined together with a dichroic interference filter interposed between the two elements. An input beam to the beam splitter is divided into a first output beam which is reflected from the filter and a second output beam which is transmitted through the filter. In order to provide a beam splitter of a generally triangular cross section in which one of the output beams has the desired spectral content for a luminance channel in the imaging apparatus and the other output beam has the desired spectral content for a chrominance channel, the interference filter is formed of alternate layers of SiO.sub.2 and TiO.sub.2 and is disposed such that an input light beam to the beam splitter has a relatively small angle of incidence on the filter.
