Abstract
A device for the collection of Raman scattered light by means of an internally reflective sphere 10 wherein a light source 12 provides light to and through a sample 16, which light is reflected back through that sample by the internally reflective sphere 10. The sample is viewed by means of a spectrograph 30 focused by lenses 26, 28 or a fiberoptic light pipe 46.
