ABSTRACT:
Two very thick plano-convex lenses with a common axis are positioned with their convex surfaces facing each other, and a radiation source and the input face of a fiber are each disposed on one of these surfaces in the vicinity of the axis.
The main feature of the device resides in the considerable thickness of the lenses relative to the radii of curvature of the dioptric faces. As a result, aberrations, in particular spherical aberrations, are reduced while the dimensions of the device are such as to enable easy construction and handling.
