A transfer mold includes a body, a first layer, and a second layer. The body has a projecting-and-recessed surface. The first layer contains an inorganic material and is disposed on the projecting-and-recessed surface of the body. The second layer contains fluorine and is disposed on a surface of the first layer. The average of hardness values of the projecting-and-recessed surface on which the first and second layers are disposed is 30 Hv or higher.

Transfer mold and manufacturing method for structure

An optical unit having an antireflection function includes a wave surface having a wavelength equal to or shorter than a wavelength of visible light. The wave surface has a curved plane which curves in a recessed shape between an apex portion and a bottom portion of the wave surface. An inflection point of an area of a cross section obtained by cutting through the wave surface in a plane perpendicular to a direction of vibration of the wave surface is positioned toward the bottom portion of the wave surface from a center of the vibration.

Optical unit, imaging device, electronic apparatus, and master

There is provided an infrared signal receiver which includes a photo-detector unit receiving light in a predetermined infrared wavelength region, sent from a remote operating unit; and an optical element disposed in front of the photo-detector unit, allowing the light of the predetermined infrared wavelength region to transmit therethrough in preference to other infrared wavelength region. In the receiver, the predetermined signal wavelength region is a region of 930 nm or longer and 960 nm or shorter, and mean transmittance of light of the optical element in the predetermined signal wavelength region is larger than mean transmittance of light in a region of 900 nm or longer and shorter than 930 nm, and/or, mean transmittance of light in a region of longer than 960 nm and 1,020 nm or shorter.
