Abstract:
An optical component of the type comprising two optically transparent bodies each having two major faces one of which is interrupted by a plurality of cavities defined by spaced apart opposing walls with inclined bottom surfaces and separated by cavity separators, in which the cavity separators between the cavities of one optically transparent body penetrate into the cavities of the other body and define for each cavity at least two voids between facing surfaces and in which said inclined surfaces of said cavity and cavity separator, respectively, come into contact with one another when said two optically transparent bodies are pressed fully together, such that said contact between said inclined surfaces of said bodies locks said bodies together in a predetermined position with respect to each other against movement in a direction parallel to the two major faces of said bodies,wherein a plane of each of said inclined surfaces intersects a plane of each of said opposing walls at an angle respectively.
