Abstract: A homogenizer includes a convex-lens array pair including a first convex-lens array disposed on a light entrance side and a second convex-lens array disposed on a light emission side. The first convex-lens array and the second convex-lens array are disposed so as to face each other such that each of the convex-lens arrays has a lens surface opposed to each other outward or inward. The first convex-lens array includes a plurality of first convex lenses in an array arrangement. The second convex-lens array includes a plurality of second convex lenses in an array arrangement. The first convex lens has an average internal transmission angle for incident light entering a lens-surface center region in the lens cross-section and being in parallel with the symmetry axis being equal to or more than 1.3 times an average internal transmission angle of a spherical convex lens.

Abstract: An optical filter is provided with a structure that contains a green coloring matter and a black coloring matter and satisfies the following requirements (i) and (ii). Further a device is provided with such an optical filter. (i) An average transmittance of light in the wavelength range of 400 to 730 nm is 2% or less. (ii) A continuous 50 nm wavelength range where an average transmittance is 80% or more exists in the wavelength range of 800 to 1000 nm.

Abstract: Provided is an adhesive for use in an ultraviolet-light-emitting device using ultraviolet light having a wavelength of from 200 to 400 nm as a light source, which can attach adherends made of a polymer having a fluorine-containing alicyclic structure with excellent adhesiveness which is unlikely to be impaired by exposure to such ultraviolet light or heat.An adhesive for forming an adhesive joint in an ultraviolet-light-emitting device, which is either the following adhesive (A) or the following adhesive (B) comprising a fluoropolymer having a fluorine-containing alicyclic structure: the adhesive (A): an adhesive in which the glass transition temperature of the fluoropolymer is from 30 to 100° C., and which does not contain an ultraviolet-shielding agent; and the adhesive (B): an adhesive comprising the fluoropolymer and an ultraviolet-shielding agent.

Abstract: A sensor cover, provided in an opening of a housing that houses a sensor, includes a conductor; a dielectric multilayer film; and a heating film, in a desired order from an outside of the housing toward an inside of the housing. The conductor and the heating film are insulated from each other. A shortest distance between the conductor and the heating film is 2.0 μm or more.
