A method includes treating a surface of a substrate to cause the surface to include a hydrophobic portion and a hydrophilic portion, providing a replication material over the hydrophilic portion, and imprinting the replication material to cause the replication material to have a predetermined characteristic.

The method regards manufacturing devices by replication, wherein each of the devices comprises a device surface. The method comprises producing the devices from a replication material by replication using a replication tool (1), wherein the replication tool (1) comprises a tool material comprising replication sites (4) comprising a replication surface (5) each. Each of the replication surfaces (5) corresponds to a negative of the device surface of a respective one of the devices. The tool material comprises, in addition to the replication sites, one or more mitigating features (7) for reducing asymmetric form errors of the device surfaces. Replication tools (1) and methods for manufacturing these are also described.

An endoscope includes an optical laminate and an image sensor. The optical laminate includes a first optical member that is a glass lens where an optical window is formed in a planar substrate, including a recessed portion or a protruding portion around the optical window, and a second optical member having a flat surface facing the substrate of the first optical member, and including a protrusion made of resin for being fitted with the recessed portion or the protruding portion. The flat surface of the second optical member is a surface of a glass substrate on the first optical member side. A resin lens of the second optical member is arranged on a surface on an opposite side of the flat surface. A flat portion excluding the optical window and the recessed portion or the protruding portion is in contact with the flat surface of the second optical member.

An optical unit includes a transparent first substrate, a transparent second substrate, a transparent first projection forming a part of an optical path, and a first aperture configured by black resin filled in a periphery of the first projection between the first substrate and the second substrate.

The present disclosure relates to a camera package, a manufacturing method of a camera package, and an electronic device capable of reducing a manufacturing cost for forming a lens. The manufacturing method of the camera package according to the present disclosure includes forming a high-contact angle film around a lens forming region on an upper side of a transparent substrate that protects a solid-state imaging element, dropping a lens material in the lens forming region on the upper side of the transparent substrate, and molding the dropped lens material by a mold to form a lens. The present disclosure is applicable to, for example, a camera package and the like in which a lens is arranged above a solid-state imaging element.

The present disclosure relates to a stacked lens structure and a method of manufacturing the same, and an electronic apparatus by which it is possible to realize miniaturization of a lens module. A stacked lens structure includes plural substrates with lens stacked on one another, the substrate with lens each having a lens disposed on inside of a through-hole formed in the substrate. In regard of side surfaces at side parts corresponding to sides of a rectangle surrounding the substrate with lens in plan view as viewed in an optical axis direction, a width and a shape are the same among all the substrates with lens, whereas in regard of side surfaces at opposite angle parts corresponding to opposite angles of the rectangle, the width or shape differs between at least two substrates with lens. The present technology is applicable, for example, to a lens module or the like.

The present invention relates to a micro-optic device for use in a micro-optic image presentation system. Specifically, the micro-optic device is formed as a single layer unitary structure arranged to generate various complex imagery effects.

A method of manufacturing a lens including forming a cover blank having cover parts by injecting a thermosetting first resin in a first mold and curing the thermosetting first resin, removing a part or all parts of the first mold, and arranging the cover blank in a second mold. The method further includes forming a lens blank having a light-shielding part between adjacent cover parts by injecting a thermosetting second resin having a greater light absorptance or light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, and obtaining individual lenses by taking out the lens blank from the second mold, and cutting the lens blank at the light-shielding part located between adjacent cover parts to obtain individual lenses each with lateral end surfaces and an upper surface of each of flange parts and lateral side walls covered by the light-shielding part.
