  • Lens system for optic temperature sensor
    Patent number: 5036194
    Abstract: An optic system (10) having a lens arrangement (38) for collimating a beam of light carried by a first array (20) of a bifurcated fiber bundle (18) to uniformly illuminate the entire surface (36) of a fluorescent material (30) to create an output signal corresponding to the temperature of the fluorescent material (30). The lens arrangement (38) focuses the output signal onto the end (34) of bifurcated fiber bundle (18) where a second array (24) communicates up to one half of the output signal generated by the glow of the fluorescent material (30) to a detector (44) which processes the output signal to inform an operator of the temperature of the fluorescent material (30).
