An improved spectroscopy illuminator (103) 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 uses a solid-state broadband white LED (107) to produce broadband light (114), which is then transmitted to a sample region (125), such as a living tissue or blood in vivo or a biological sample in a spectrophotometer target region. The solid-state source keeps both the illuminator and sample cool during operation, allowing the illuminator to be integrated into the tip of a medical probe, a medical system such as an oximeter, or other monitoring systems or devices making measurements based on light scattering, absorbance, fluorescence, phosphorescence, Raman effects, use of a contrast agent, or other known spectroscopy techniques. Systems incorporating the improved illuminator, and methods of use are also disclosed.
