A deformation of a stacked lens is suppressed. A stacked lens structure has a configuration in which substrates with lenses having a lens disposed on an inner side of a through-hole formed in the substrate are bonded and stacked by direct bonding. The present technique can be applied to a camera module or the like in which a stacked lens structure in which at least three substrates with lenses including first to third substrates with lenses which are substrates with lenses in which a through-hole is formed in the substrate and a lens is formed on an inner side of the through-hole is integrated with a light receiving element, for example.

A method for making glass material lens array, comprising: Step 1: providing a mold device, an upper mold, a lower mold a plate structure having plate body and through holes, and a plurality of lenses having lens body portions and annular portions; Step 2: placing the plurality of lenses on the lower mold cavities of the lower mold; Step 3: disposing the plate structure between the upper mold and the lower mold, to align the through holes with the lenses; Step 4: moving the plate structure downward, to have the lenses received within the through holes; Step 5: closing the upper mold and the lower mold, to make the upper mold pressing region abut and press the plate body; and Step 6: forcing and squeezing the plate body of the plate structure to deform, and generate a deformed region B flowing and covering a periphery of the annular portion.

A method includes depositing a glass frit on sidewalls of a plurality of cavities of a shaped article formed from a glass material, a glass ceramic material, or a combination thereof. The glass frit is heated to a firing temperature above a glass transition temperature of the glass frit to sinter the glass frit into a glaze disposed on the sidewalls of the plurality of cavities.

A method includes applying a polymer to a mold, the mold having microstructures with the polymer flowing into the microstructures when applied to the mold. The method includes pressing an inorganic substrate onto the polymer. The method includes curing the polymer to fix the polymer to the inorganic substrate to form an optical element from the polymer and the inorganic substrate, the optical element having microstructures formed by the microstructures in the mold. The method includes releasing the optical element from the mold.

The present technology relates to, for example, a lens attached substrate including a substrate which has a through-hole formed therein and a light shielding film formed on a side wall of the through-hole and a lens resin portion which is formed inside the through-hole of the substrate. The present technology can be applied to, for example, a lens attached substrate, a layered lens structure, a camera module, a manufacturing apparatus, a manufacturing method, an electronic device, a computer, a program, a storage medium, a system, and the like.

A method of producing optical components includes providing an initial carrier including cutouts; carrying out a molding process to form transparent optical molded parts arranged in the cutouts of the initial carrier, wherein a molding compound is introduced into the cutouts of the initial carrier and the molding compound is molded and cured; and singulating the initial carrier including the optical molded parts so that separate optical components are formed that respectively include a carrier produced from the initial carrier and including a cutout, and an optical molded part arranged in the cutout.

A method of making optical diffuser elements (20) includes providing a substrate (100) composed of a polymer material and having openings (102) therein. An optical diffuser material (110) is dispensed into the openings (102), and the optical diffuser material (110) is hardened to form a sheet (200) composed of regions of the optical diffuser material (110) surrounded laterally by the polymer material. The method includes separating the sheet (200) into multiple optical diffuser elements (30) that retain their mechanical stability and optical properties when subjected to a reflow process.

Methods for forming optical articles with antireflective nanostructured (ARN) surfaces. An aluminum layer is deposited or otherwise applied to the cavity of an injection mold tool. Sequential chemical treatments such as anodization and etching steps form an ARN mold texture on the interior surface of the cavity. The ARN mold texture is a negative of a desired surface texture of the article. During injection molding, the desired ARN surface is thereby produced in the optical article.

A method includes depositing a glass frit on sidewalls of a plurality of cavities of a shaped article formed from a glass material, a glass ceramic material, or a combination thereof. The glass frit is heated to a firing temperature above a glass transition temperature of the glass frit to sinter the glass frit into a glaze disposed on the sidewalls of the plurality of cavities.

To suppress occurrence of contamination or damage to a lens. In the present technology, for example, a manufacturing apparatus allows a spacer which is thicker than a height of a lens resin portion protruded from a substrate to be adhered to the substrate. In addition, for example, in the present technology, the manufacturing apparatus molds the lens resin portion inside a through-hole formed in the substrate by using a mold frame configured with two layers of molds and, after molding the lens resin portion, in the state that one mold is adhered to the substrate, the manufacturing apparatus demolds the substrate from the other mold. The present technology can be applied to, for example, a lens-attached substrate, a stacked lens structure, a camera module, a manufacturing apparatus, a manufacturing method, an electronic apparatus, a computer, a program, a storage medium, a system, or the like.
