Abstract : An object of the invention is to obtain the advantage of a long light path for more optical materials than is feasible with optical fibers to provide an optical dosimeter. According to the invention, a reflecting optical dosimeter is a thin block of optical material having an input light pipe at one corner and an output light pipe at another corner, arranged so that the light path includes several reflections off the edges of the block to thereby greatly extend its length. In a preferred embodiment, one corner of the block is formed at an angle so that after the light is reflected several times between two opposite edges, it is then reflected several more times between the other two edges.
