Abstract
A viscous light transmissive fluid material, such as glycerine or the like, is applied to the solid end portion of a light conducting member of a light probe for optically coupling the latter with a sample having an irregular glossy surface. The fluid interface substantially reduces specular reflection from the glossy surface of the sample and also provides effective optical coupling between the sample and the light conducting member, both of which may have surface irregularities or may be misaligned with respect to each other.
