Abstract: An optical component mounting device and method is disclosed where the optical components are disposed within a thin-walled tube and the tube is configured to produce an interference fit within the cylindrical opening of a mounting sleeve. The optical components are secured to the tube such that their optical axes coincide with the tube longitudinal axis. Mating of the optical mounting assembly to external reference surfaces precisely locates and aligns the optical axes with respect to an external reference axis. The optical mounting assembly provides at least two degrees of freedom to the optical components for facilitating alignment.

Abstract: Disclosed is a laser print head, suitable for use with a recording medium, comprising a print head base comprising a plurality of mounting surfaces, one or more optical radiation source removably affixed to a first base mounting surface, at least one collimating lens, at least one focusing lens affixed to a second base mounting surface, a pre-objective lens affixed to a third base mounting surface; an objective lens, and one or more optional mirror facets.

Abstract: A device for redirecting beams of light emitted from different sources includes: a monolithic stationary substrate having alignment surfaces for aligning the device for mounting into a system; multiple facets resident on the substrate including at least two facets having surfaces for redirecting the beams of light emitted from different sources; and facet edges on the substrate demarcating each of the multiple facets from one another, the edges providing outside corners greater than .pi. radians between surfaces of adjacent multiple facets. The surfaces of the multiple facets are preferably surfaces of revolution created by cutting the facet surfaces while the device is rotated about a common axis, for instance, by machining via single diamond point turning.
