Abstract

PURPOSE:To uniform the optical characteristics and to reduce the production cost, by forming the comparatively small lamellar lenses with the same metallic mold and using these lenses in combination. CONSTITUTION:The lens units A of transparent synthetic resin are formed with the same metallic mold and then used in combination via joint parts 1 and 2. In such way, a lamellar lens having a necessary size is obtained easily to reduce the production cost.
