Abstract: A glass sheet is a single glass sheet having a first surface and a second surface facing the first surface. The glass sheet has a curvature part curved in a first direction and a second direction orthogonal to the first direction. A radius of curvature in the first direction of the curvature part is 8,500 mm or less. At least a part of the first surface has been chemically strengthened in the curvature part. In the first direction within the chemically strengthened region in the curvature part, an Na amount in the first surface is smaller than the Na amount in the second surface.

Abstract: A microlens array to be used in combination with a pixel array of an imaging element. The microlens includes a glass substrate; and a plurality of microlenses provided on at least one surface of the glass substrate and arranged in an array shape. Each of the plurality of the microlenses is constituted such that light to be entered into the microlens is received by a plurality of pixels of the imaging element. A difference between a coefficient of linear expansion of the glass substrate and a coefficient of linear expansion of an imaging element substrate having the pixel array formed thereon or member of a package to be bonded to the imaging element substrate is within 8×10−6 (/K).

Abstract: An optical device includes a base material including a surface on which multiple concaves are formed. The concaves include respective curved surfaces. The concaves are formed so that the bottoms of the concaves are at two or more different positions in a depth direction. In the optical device, 2/7≦|(n1−n2)×Δd|/λ≦10 holds, where n1 is the refractive index of the base material, n2 is the refractive index of a medium around the concaves, λ is the wavelength of a beam flux that enters the base material, and Δd is a range of the positions of the bottoms in the depth direction.
