Abstract: A multi-spectral variable focus illuminator. The illuminator includes a plurality of first light sources arranged in a first array, each of the first light sources capable of emitting light in a first wavelength band, and a plurality of second light sources arranged in a second array, each of the second light sources capable of emitting light in a second wavelength band different from the first wavelength band. The illuminator includes an array of lenses positioned in front of the light sources. The relative positions of the lens array and the first and second light sources are changeable such that the field illuminated by the first light sources varies in size with the relative positions of the lens array and the first light sources, and the field illuminated by the second light sources varies in size with the relative positions of the lens array and the second light sources.

Abstract: Optical apparatus for displaying enlargements of graphic copy includes a platform carrying a television camera having an optical pickup lens. The platform is rotatable on a horizontal axis. An arm is secured to the platform and extends downwardly toward the copy. A frame is pivotably secured to the arm to bear on the copy and outline an image scanning field. A mirror is pivotably secured to the platform and is adjustable in an optical path including the lens and frame. The platform has depending legs carrying wheels or casters. A handle on the arm facilitates lifting the frame off the copy and moving the apparatus in a horizontal plane.
