ABSTRACT:
An apparatus is disclosed for measuring the refractive index of index matching gels. A light source (10) is directed into one (20) of the output legs (20, 22) of an optical splitter (18), where the input leg (26) is interconnected to a fiber optic cable (27). The end of the cable (27)is inserted into the gel (30) to be measured. The incident light source (10) directs an incident light source through the splitter, and through the end (29) of the fiber optic cable (27). The difference in refractive indexes between the fiber optic cable (27) and the gel (30) causes a reflection of the incident light back to the splitter (18) and through a measuring device (52). By measuring the reflected power, and by knowing the incident power and other known factors, the refractive index of the gel can be calculated.
