Gradient-index lens, and method for producing the same

Image Number 10 for United States Patent #6903877.

A micro prismatic structure is formed inside the light transmission face of a gradient-index lens, in which the projections have a height of at least 0.25 .lambda. and the distance between the neighboring projections is at most .lambda., based on the applied wavelength .lambda.. Preferably, the micro prismatic structure has conical projection units that are aligned in the light transmission face of the lens in a mode of hexagonal, tetragonal or orthorhombic arrangement. The conical projections may be in any form of circular cones, polygonal cones, flat-headed circular cones (circular cones of which the apex has been cut horizontally) or flat-headed polygonal cones .
