ABSTRACT:
A relatively viscous light transmissive liquid material, such as glycerine or the like, applied to the solid end portion of a light conducting member enhances the optical coupling with a sample or object having an irregular and/or glossy surface to be optically examined. Moreover, the light probe system has a test end with a tip for substantial abutment with a test area or test point of a sample. The tip provides point or primary illumination of the test point and a further source of general or secondary illumination is provided the sample annularly about the probe tip and test point so that upon illumination of the sample ambient lighting effects are simulated.
