Spectroscopy light source
First Claim
1. A spectroscopy light source for use in spectroscopy systems that measure the light absorption characteristics of a target, comprising:
- (a) alight source (b) a block formed of a material allowing light transmission therethrough, the block formed with a luminescent material therein, wherein the block has a target surface through which light may pass onto the target and a reflective surface being formed with a reflective surface thereon to reflect escaping light back onto the target.

Abstract
A light source for a spectroscopy unit that measures tissue includes a block for engaging tissue and a light source. The block is formed of translucent material. The light source is positioned in close proximity to the block either directly or through use of a light fiber. The light source produces light at a single wavelength or small range of wavelengths shorter than the desired range of wavelengths to be produced by the light source for the spectroscopy unit. A luminescent material is placed in the light path between light source and the tissue to produce the desired wavelength of light when pumped by the light source.
