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.
