  • Patent number: 5315384
    Abstract: A color line scan video camera (50) for inspecting articles (18) includes a prismatic beam splitter arrangement (52) that receives a wide spectrum of visible light from a variable magnification objective lens arrangement (54) to provide improved multi-color inspection capability. The prismatic beam splitter separates the light received from the scanned articles into three preselected spectral bands of light, each of which is imaged upon a different charge-coupled device line scan sensor that generates a corresponding color component video signal. The light transmission characteristics of the lens are "color-corrected" to transmit uniformly the light received from the scanned articles.
