Rugged optical head enables remote, nonintrusive measurements of temperatures and chemical compositions in hostile environments. Head brings laser light to system under test and carries system-scattered light to spectrograph or other instrument. Optical head beams light from laser source to test chamber, then collects backscattered light from chamber and sends it to spectrographic equipment. Lenses, prisms, and optical-fiber tips moved so that focal point precisely positioned in test chamber.
