MANUFACTURE OF LENS ARRAY AND LENS ARRAY

摘要

PROBLEM TO BE SOLVED: To efficiently and inexpensively provide lens arrays superior in an optical characteristic by forming a resin molded good where plural lenses are arranged in plural columns and are integrally connected with synthetic resin having translucency and dividing the resin molded good as plural lens arrays where the plural lenses are arranged in columnar forms. SOLUTION: A resin molded good 1' is made into a plate form or a sheet form whose outline form is rectangular and it is formed by synthetic resin having translucency. Plural lenses 11 are constituted so that confronted concave curve faces are formed in plural parts on the surface and the rear face of the resin molded good 1' and are the double convex lenses where the concave curve faces are set to be faces for light incident/ejection. The cutting work of such resin molded good 1' is executed. The cutting work can be executed by sequentially or simultaneously cutting the resin molded good 1' along the virtual lines of codes Nb-Nb, which are equivalent to the band-like areas 1e of plural rows between lens columns. The plural lens arrays 1 of long block forms can be obtained with such cutting work.
