LENS ASSEMBLY

摘要

PURPOSE: Lens assembly is provided to prevent diffuse reflection light by narrowly forming a penetration hole towards an image side and to minimize the generation of a flare phenomenon. CONSTITUTION: A first lens(110) has a lens surface(112). A second lens(120) has a lens surface(114). The second lens is nearly arranged to an image side. The first lens is nearly arranged to an object side. A spacer(130) is installed between the first lens and the second lens. The spacer maintains an interval between the first lens and the second lens as a predetermined distance. The spacer has a penetration hole which becomes narrow toward the image side. The penetration hole is located on an optical shaft. A cover glass(150) is installed between the second lens and an image formation surface.
