ABSTRACT:
An optical connector for connecting photometric analysis equipment which includes a transmitting and receiving light pipe to a material such as flowing blood wherein the blood is not contaminated by the light pipe. The connector has a flow passage therethrough for connection to the blood flow conduit and a light pipe receiving passage extending at a right angle thereto. At the intersection of the passages there is provided an image transferring window, and the light pipe is arranged to be snugly received in the pipe receiving passage in abutment with the window. The image transferring properties of the window are such that no optical distortion occurs as light is transmitted from one face to the opposite face thereof. This is accomplished by forming the window of a coherent bundle of optical fibers of very small individual diameters in the order of 0.003 inches or less.
