摘要： An adhesive with a refractive index of 2.0 and over is transparent at an infra-red band. A production method of the adhesive and a beam splitter prism set is provided. The beam splitter prism set separates middle and far infra-red beam paths for electro-optical monitoring systems according to wavelengths of the middle and far infra-red beam paths, wherein in the electro-optical monitoring systems the adhesive is used.

摘要： An optical imaging system includes a first lens having positive refractive power, a second lens, a third lens, and a fourth lens, arranged sequentially from an object side along an optical axis. The first lens through the fourth lens are spaced apart from each other along the optical axis in a paraxial region. A total focal length f of a lens unit including the first lens through the fourth lens and half (IMG HT) of a diagonal length of an imaging surface of an image sensor satisfy f/IMG HT>4.9. An effective aperture radius of an object-side surface of the first lens and an effective aperture radius of an object-side surface of the second lens are both greater than effective aperture radii of an object-side surface and an image-side surface of each of the lenses other than the first lens and the second lens.

摘要： A projector includes a light source, a separation optical system including a first dichroic mirror for separating multicolored light into a first colored light beam as a blue light beam and another colored light beam, a first light modulation element for modulating the first colored light beam, a second light modulation element for modulating the other colored light beam, a reduction optical system for reducing a luminous flux width of the first colored light beam modulated by the first light modulation element, a color combining prism, and a projection optical system. The effective area of the first light modulation element is larger than the effective area of the second light modulation element. The separation optical system includes an extension optical system for extending a light path.

摘要： The disclosure relates to an optical system for an augmented reality apparatus, comprising: an image projection source; and a polarizing beam splitter. The polarizing beam splitter is arranged such that light emitted from the image projection source is able to be non-perpendicularly incident on the beam splitting side and be at least partially reflected. The polarizing beam splitter is configured such that a polarized light component passes through the polarizing beam splitter and is transmitted through the transmission side thereof, and a polarized light component is reflected from the beam splitting side. The optical system also comprises a polarizer disposed between the image projection source and the polarizing beam splitter, and the polarizer is configured to allow polarized light, whose polarization is in the second direction, to be transmitted therethrough and polarized light, whose polarization is in the first direction to be absorbed.

摘要： A first dichroic beamsplitter is deployed in a first prism on a plane oblique to a light-wave entrance surface. A second dichroic beamsplitter is deployed in a second prism on a plane oblique to a light-wave entrance surface such that polarized light in a first polarization state relative to the first dichroic beamsplitter is in a second polarization state relative to the second dichroic beamsplitter. The first dichroic beamsplitter transmits polarized light of a first color in the first polarization state relative to the first dichroic beamsplitter, and reflects polarized light of a second color in the first polarization state relative to the first dichroic beamsplitter. The second dichroic beamsplitter transmits polarized light of the first and second colors in a second polarization state relative to the second dichroic beamsplitter, and reflects polarized light of a third color in the first polarization state relative to the second dichroic beamsplitter.

摘要： An optical device includes a lightguide having a first pair of external surfaces parallel to each other, and at least two sets of facets. Each of the sets including a plurality of partially reflecting facets parallel to each other, and between the first pair of external surfaces. In each of the sets of facets, the respective facets are at an oblique angle relative to the first pair of external surfaces, and at a non-parallel angle relative to another of the sets of facets. The optical device is particularly suited for optical aperture expansion.

摘要： The disclosure relates to an optical system for an augmented reality apparatus, comprising: an image projection source; and a polarizing beam splitter. The polarizing beam splitter has a beam splitting side adjacent to the image projection source and a transmission side facing away from the image projection source. The polarizing beam splitter is arranged such that light emitted from the image projection source is able to be non-perpendicularly incident on the beam splitting side and be at least partially reflected. The polarizing beam splitter is configured such that when light is incident on the beam splitting side, a polarized light component passes through the polarizing beam splitter and is transmitted through the transmission side thereof, and a polarized light component is reflected from the beam splitting side. The optical system also comprises a polarizer disposed between the image projection source and the beam splitting side of the polarizing beam splitter.
