Abstract

PURPOSE:To obtain superior chemically durable quality by immersing lens arrays into a molten salt contg. metallic ions of good chemical durability. CONSTITUTION:Glass lens elements 2 consisting of many pieces of focusing optical transmission bodies are arranged in proximity in such a way that respective optical axes are parallel with each other, and the spacings between these and the circumference thereof are solidified with a black plastic resin 3 to one body. After both surfaces of such lens arrays 1 are polished, these are immersed in a molten salt 5 contg. metallic ions of good chemical durability. For example, an eutectic salt of CuCl-SnCl2 (35.7mol% CuCl, 171.7 deg.C eutectic point) or an eutectic salt of SnCl-ZnCl2 (43.9mol% ZnCl and 171 deg.C eutetic point) is used for the molten salt. Said lenses are immersed under conditions of <=200 deg.C and 30min 6hr (more preferably within 3hr).
