  • Multi-spectral filter
    Patent number: 5164858
    Abstract: An optical thin film filter for the spatial and spectral separation of two or more transmitting bands of radiant energy. For a two band filter the filter has a substrate substantially transparent to radiant energy in the transmitted bands. On one surface of said substrate is a multilayer interference coating that transmits both wavelength bands of interest. On the other surface of said substrate (or on the same surface) are two sets of non-overlapping butted, parallel stripes with one set being alternately interspersed with the other. The widths of said stripes are varied to provide for precisely defined regions of spatial and spectral delineation. One set of stripes is capable of transmitting one of the bands of interest and reflecting all others, while the second set of stripes is capable of transmitting at least one band different from the one band transmitted by said first set of stripes and reflecting all others.

  • Method for making pigment flakes
    Patent number: 4879140
    Abstract: A method for producing pigment flakes in the shape of thin plates. A chamber is provided which is placed under vacuum and a gas, which is capable of forming a plasma upon its exposure to a plasma generating device, was fed to the interior of the chamber device. The plasma is created within the chamber which forms a film upon a surface within the chamber. The film is converted to flakes which are then removed from the interior of the chamber.
