摘要： A spectrophotometric instrument is comprised of a processor, a probe (402) having a tissue engaging surface (404) with an aperture (422) therethrough and a light source producing measurement light signals and optically coupled to the probe via a first optical path (420). A partially reflective first reflecting member (430) is located in the probe and has a generally elliptical profile positioned to reflect a first portion of the measurement light signals to the tissue aperture and to transmit a second portion of the measurement light signals through the first reflecting member. A second reflecting member (456) is located in the probe and has a generally elliptical profile positioned to reflect the measurement light signals transmitted through the first reflecting member. A second optical path (428) has a distal end positioned in the probe to receive to receive light signals transmitted through the tissue sample and a proximal end coupled to the processor.
