Abstract

Recently, the optical technology has progressed with various kinds of materials. The graded index optical materials are expected as rod lens, low chromatic aberration lens, and high bandwidth optical fibers^1)-3) etc. Nowadays, most of practically used GRIN material are made by inorganic materials. On the other hand, it has been reported that the GRIN material can be synthesized by organic material more easily and mildly than inorganic materials⁴⁾. Regardless of the inorganic or organic materials, the GRIN materials so far have only the small size in diameter as ϕ =10 mm, which is too small to be used as eyeglasses or camera lenses.
