Abstract
A scanner (40) is disclosed which includes a source of coherent light (12), a radial holographic deflector (16), a F.theta. lens (62), which images a scanned spot onto an image plane (18). The F.theta. lens (62) is comprised of a decentered aspheric mirror (64) and a diffractive--refractive toroidal lens (66). The apparatus is relatively insensitive to variations in the wavelength of the source of coherent light.
