摘要： A lens mirror array includes a plurality of transparent optical elements integrally connected to each other in one direction. Each of the optical elements includes: an incidence side lens surface on which light is incident; an exit side lens surface through which incident light exits; and a flange portion having a surface continuous to the incidence side lens surface. The surface of the flange portion is arranged at an angle at which unnecessary light incident on the flange portion is guided to a position deviating from an slit, the slit allowing transmission of effective light in light that exits through the exit side lens surface.

摘要： A lens mirror array includes a plurality of optical elements connected to each other and aligned along one direction. Each of the optical elements comprises a first lens surface on which light is incident, a first reflection surface on which the incident light is reflected within the optical element, a second reflection surface on which the reflected light is further reflected within the optical element, a second lens surface through which the light reflected by the second reflection surface is emitted outside the optical element, and a protruding portion having a plurality of surfaces and connected to the first lens surface and the second reflection surface. One of the surfaces of the protruding portion inclined with respect to a direction of light incident on the protruding portion has a prism structure.

摘要： An imaging element array includes a plurality of imaging elements that are arranged side by side. Each imaging element is integrally molded as a single piece element and includes an incident surface, an emission surface, and a plurality of reflective surfaces which are provided between the incident surface and the emission surface. The imaging element includes a first reflective element and propagation preventing surfaces. The first reflective element includes at least one of the plurality of reflective surfaces and has an effective region which is in contact with adjacent imaging elements. The propagation preventing surfaces are to either side of another one of the plurality of reflective surfaces and are positioned to prevent light rays other than light rays reflected from the reflective surface from propagating to the emission surface.

摘要： According to at least one embodiment, a lens mirror array includes a plurality of optical elements. An optical element of the plurality of optical elements includes an incident surface on which light is incident, an emitting surface configured to emit the light incident through the incident surface, at least one reflecting surface reflecting the light incident through the incident surface toward the emitting surface, and a light shielding portion configured to block the light. The incident surface includes an effective surface configured to pass effective light emitted from the emitting surface and a directional surface configured to direct unnecessary light to the light shielding portion.

摘要： An imaging element array includes a plurality of imaging elements that are arranged side by side. Each imaging element is integrally molded and includes an incident surface, an emission surface, and a plurality of reflective surfaces which is provided between the incident surface and the emission surface. The imaging element includes a first reflective element. In the first reflective element, at least one of the plurality of reflective surfaces is formed on a top of a convex portion which protrudes outwardly and has reflective sidewalls extending therefrom. In the first reflective element, a width of the reflective surface, which is formed on the top of the convex portion, in an arrangement direction thereof is less than a distance from an entrance into the concave portion to the top of the convex surface.

摘要： An optical array includes one or more optical elements each including an incident surface at which light is incident into the optical element, a first reflection surface at which the light passing through the incident surface is reflected, a second reflection surface at which the light reflected by the first reflection surface is reflected again, an emission surface at which the light from the second reflection surface exits the optical element, and a refractive surface at which light that passes through the first reflection surface is refracted away from the emission surface.

摘要： An optical device includes a lens mirror array, in which transparent optical elements are connected to each other along a first direction, and a case, in which the lens mirror array is contained and fixed. The case includes at least three holes through which a manufacturing jig can pass. The jig can be used to press the lens mirror array in a direction intersecting the first direction at three or more positions on the lens mirror array to deform the lens mirror array to correct for possible distortions in the optical device prior to the fixing of the lens mirror array to the case.
