Abstract:
A lens module capable of preventing a deterioration of optical properties and a method for manufacturing thereof are provided. Optical axes of lens portions of superimposed lens arrays are aligned. Substrate portions of the other lens arrays of the superimposed lens arrays except the lowermost lens array are cut by a first cutting portion. Subsequently, thermosetting resins are supplied from a gap between cut surfaces of the cut substrate portion so as to fill a gap between the substrate portions of the superimposed lens arrays with the thermosetting resins and to cause the thermosetting resins to integrally cover the cut surfaces of the substrate portion and a surface of the substrate portion of the uppermost lens array. Thereafter, the thermosetting resins are cured, and an individual lens module is separated by cutting the substrate portion of the lowermost lens array using a second cutting portion.
Abstract:
Provided is a stack-type lens array capable of preventing a lens from peeling off due to stress during dicing or vibration and impact when used. The stack-type lens array is formed by stacking and bonding two lens sheets in which micro lenses are arranged on a flat portion at predetermined intervals. Antireflection films are vapor-deposited on a convex surface and a concave surface of the lens and a light shielding film is vapor-deposited such that a circular opening is formed at the center of the concave surface. The opening serves as a diaphragm aperture of the lens. An exposed surface in which neither the antireflection film nor the light shielding film is vapor-deposited is provided outside the light shielding film between adjacent lenses. A dicing line is set at the center of the exposed surface. An adhesive layer is formed in a predetermined pattern on the exposed surface.
