ABSTRACT:
A radiation transmission fiber for spectroscopic monitoring includes a transmission portion and a sensor portion; the transmission and sensor portions have a continuous core portion and continuous cladding over the core portion throughout the transmission and sensor portions; the sensor portion of the core is of smaller diameter than the transmission portion(s) and is connected to the transmission portion(s) by a conical transition portion(s); and the cladding in the transmission portion is of greater thickness than the cladding in the sensor region.
