Abstract
An improved illuminator for generating broadband light, and for delivering the light to a sample with an improved delivery efficiency, for higher optical density and/or reduced thermal transfer, than achieved with conventional halogen bulb sources. The illuminator enables spectroscopic analysis in thermally-sensitive or spatially-constrained environments. A phosphor-coated broadband white LED and integrated collimating optics produces a continuous, collimated broadband light beam from 400 nm to 700 nm, which is then transmitted through space to a sample region, such as a living tissue in vivo. This results in a high net efficient delivery of light to the tissue sample. An efficient conversion of power to light, and the high delivery efficiency, keeps both the illuminator and sample cool during operation, allowing the illuminator to be integrated into the tip of a medical probe or into monitoring systems.
