Abstract
Spectroscopic probe light shields coupled to the end of an optical probe improve user safety, reduce unwanted stray light and enhance signal collection from a liquid or gaseous sample. Apertured inner and outer baffles with offset perforations allow a sample to flow through the baffles and past a counter-propagating focused or collimated excitation/collection beam. The spectroscopic probe may be a Raman or fluorescence probe, operating in the UV-visible or mid-IR region of the spectrum. The inner shield may include a retro-reflector to amplify light collection from the sample, or the inner shield may include a light absorber to reduce the intensity of a scattered excitation beam. One or both of the inner and outer shields may be cylindrical, and the apertures in the baffles may be slots, circles or other shapes. The baffle(s) may be adapted for temporary, permanent, or semi-permanent attachment to the distal end of the probe optic.
