MICRO LENS AND MICRO LENS ARRAY

摘要

A micro lens array (10), comprising a plurality of two-dimensionally arranged micro lenses (3) having lens parts (1) and base parts (2). The array provides a generally flat plate-like appearance. The lens part (1) is formed in a cylindrical shape with a specified diameter and comprises an amorphous part (1a) formed of an amorphous glass positioned on one surface side of the micro lens array (10) and a crystalline part (1b) formed of a crystallized glass positioned on the other surface side. The surface of the amorphous part (1a) is raised in curved shape from the position of the surface of the base part (2) to form a convex-shaped lens surface (1a1). The base part (2) is formed of the same crystallized glass as the crystalline part (1b) of the lens part (1) and surrounds the periphery of the lens part (1).
