  • System for selectively controlling the spectral make-up of visible light from a source thereof
    Patent number: 5333034
    Abstract: A preferred photographic printer (10) includes light filters (52, 54, 56) which can be shifted to selected positions for filtering respective spectral components from selected portions of a light beam (100) in order to vary the spectral make-up of the light beam, and further includes a preferred metal halide lamp (48) which produces a spectral output with substantial portions in the visible band.

  • Integrator for analyzing the spectral content of printing illumination
    Patent number: 4494876
    Abstract: An integrator for spectral analysis of printing illumination from photographic film including a lens for collimating the printing illumination into a beam. The integrator includes first and second color separation filters which divert respective colors from the beam. First and second phototransducers are provided for receiving the respective colors. A third phototransducer receives the beam passing through the first and second filters. Each phototransducer produces a signal representative of the intensity of the respective color.
