Abstract
An ophthalmic illuminator includes a one or more light combining stages arranged in series to augment a white light source with various color spectral bands. A first stage combines white light from a white light source with colored light from a first color source. Each subsequent stage in the series adds its own respective colored light. The color sources may be selectively turned on/off or driven with variable amounts of power. In this fashion, a combined light is produced by the final stage that represents a desired chromaticity and brightness as desired for a particular ophthalmic therapeutic procedure.
