Abstract:
A light source device includes: a first light source that emits light of first linear polarization; a half mirror that separates emitted light from the first light source into first light traveling to a first optical path and second light traveling to a second optical path; a polarized light combination mirror that combines the first light and the second light; an optical path change element that is disposed on the second optical path and reflects the second light and guides the second light to the polarized light combination mirror; and a retardation plate that is disposed on the second optical path and converts the second light into second linear polarization inclined with respect to the first linear polarization. The optical path change element is disposed such that point images of the first light and point images of the second light on the polarized light combination mirror are alternately arranged.
Abstract:
A light source device includes: a first light emitting device including a plurality of first solid-state light emitting elements arranged at a regular interval in a two dimensional array form; a second light emitting device including a plurality of second solid-state light emitting elements arranged at a regular interval in a two dimensional array form; and a first light combining plate including a first region and a second region, the first region transmitting first light beams emitted from the plurality of first solid-state light emitting elements of the first light emitting device, the second region reflecting second light beams emitted from the plurality of second solid-state light emitting elements of the second light emitting device. Beam arrangement of (i) the first light beams transmitted through the first light combining plate and (ii) the second light beams reflected by the first light combining plate form a closest packed array.
Abstract:
An optical lens is composed of a nanocomposite material including a resin material and nano-fine particles dispersed in the resin material. The nano-fine particles include indium tin oxide, and Ag or Au. The optical lens has improved performance of compensating chromatic aberration, enables further downsizing of lens barrels, and realizes improved transparency and reduction in scattered light by the nano-fine particles.
Abstract:
An optical material is composed of a resin material and inorganic fine particles dispersed in the resin material. The inorganic fine particles contain at least gallium phosphate fine particles. An optical element is formed of the above-described optical material. A hybrid optical element includes a first optical element and a second optical element disposed on an optical surface of the first optical element. The second optical element is the above-described optical element.
