Abstract
An instrument that analyzes chemical properties of a specimen includes a probe that is used in place on the specimen for spectroscopic analysis. The probe has a probe body with a proximal end and a distal end, and a first optical fiber extends from the proximal to the distal ends. A temperature sensor is included in the probe body and is used so insure that the probe does not exceed a rated temperature limit or to monitor specimen temperature while, simultaneously, chemical composition information of the specimen is transmitted by the optical fiber. The probe can be inserted into a container holding the specimen and can yield both temperature and chemical composition information. The probe includes a plurality of metal coated fibers with the distal ends of the fibers positioned inside a bore in the probe. Braze material is placed on the probe near the bore and the braze material is then brazed to the metal coating on the ends of the fiber.
