Abstract
In a fiber optic probe for an infrared analysis instrument, a window block made of sapphire is provided having an inner face in the shape of a truncated cone. A fiber optic cable has its distal end adjacent to the inner face of the window block and the optic fibers in the distal end are segregated into transmitting fibers adjacent to said conical section of the inner face of the window block and receiving fibers abutting the central circular portion formed by the truncated cone shape of the inner face. A cylindrical separator separates the receiving and transmitting fibers at the distal end of the fiber optic cable.
