Provided are gold-coated flat silver particles, a dispersion including the gold-coated flat silver particles and a dispersion medium, a method of the dispersion, a coating film including the gold-coated flat silver particles, and an antireflection optical member. The gold-coated flat silver particles include flat silver particles and a gold coating layer, in which an average thickness of the gold coating layer on principal planes of the particles is 0.1 nm to 2 nm, and a ratio of the average thickness of the gold coating layer on the principal planes of the particles to an average thickness of the gold coating layer on edge surfaces of the particles is 0.02 or higher.

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.

Stack-type lens array and lens module

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.

Lens module and method for manufacturing thereof

Disclosed are a wafer-level lens array, a method of manufacturing a wafer-level lens array, a lens module, and an imaging unit that can prevent the influence of, for example, the shrinkage of a forming material, prevent the positional deviation between lenses when the wafer-level lens arrays overlap each other or when the wafer-level lens array overlaps an imaging element array, and be easily designed. A method of manufacturing a wafer-level lens array including a substrate unit and a plurality of lens units that is arranged on the substrate unit includes: forming the substrate unit; and integrally forming the lens units that are made of a resin having substantially the same optical characteristics as a material forming the substrate unit with the substrate unit.

Wafer-level lens array, method of manufacturing wafer-level lens array, lens module and imaging unit

A wafer lens array comprising a plurality of lens sections arranged one-dimensionally or two-dimensionally, a substrate section connecting the lens sections, and gap sections, wherein the lens surfaces in the lens section each have one or more curved surfaces; the gap section is a part projecting from outside than the inner edge of the lens section; and the inner surfaces of the gap sections are spread from a side near the lens section to the other side.

Wafer lens array and method for manufacturing the same

Provided is a wafer lens unit comprising a plurality of wafer lens arrays, wherein the wafer lens array comprises a plurality of lenses arranged in one dimension or two dimensions and a substrate interconnecting the lenses; and the neighboring wafer lens arrays are bonded through an adhesive layer comprising a spacer only at the substrates thereof.
