  • Infrared filter
    Patent number: 5426532
    Abstract: An infrared filter that is formed as a laminated structure including a plurality of layers having substantially uniform thicknesses. The various embodiments include first layers that are relatively thick which are interleaved with second layers that are relatively thin as compared to the first layers. The second layers are generally one quarter wavelength optical thickness at a particular tuned wavelength, whereas the first layers are generally a plurality of quarter wavelength optical thicknesses. Methods for manufacturing the filters are described, including grinding and polishing procedures for obtaining the desired uniformity of thicknesses of said layers.
    Type: Grant
