摘要： The present invention relates to a lens system for a head-up display. The technical gist of the present invention is to provide a lens system for a head-up display, comprising: a first group of lenses positioned toward a screen with reference to a diaphragm; and a second group of lenses positioned toward an image element, wherein each lens is combined/arranged such that the DN/DT (abs.) (temperature coefficients of refractive index (10−6/° C. at 632.8 nm)) value of a lens that satisfies |P|>=40 (P is refractive power of each lens), among the plurality of lenses constituting the first and second groups of lenses, has a positive number value or a negative number value according to the refractive power, and the lens system accordingly has thermal compensation characteristics by controlling the amount of change in the focal distance of each lens. Accordingly, the present invention advantageously provides a lens system for a head-up display wherein the DN/DT value, which follows the refractive power of each lens, is arranged/designed appropriately such that temperature-based thermal compensation characteristics are satisfied by controlling the amount of change in the focal distance of each lens.

摘要： An optical system for a head-mounted display in which image rays provided from a display device are divergent to form and provide an enlarged image is configured so that first and second lenses are sequentially disposed from an object along an optical axis and provide the enlarged image on an image plane, and angles of principal rays are gradually increased from the optical axis toward the edge of the image plane. Thus, as the angles of principal rays are increased, an angle of view is improved to provide a large screen so that it is possible to appreciate a vivid image due to an increase in the sense of presence and the degree of involvement. The entire size of the optical system can be reduced. The head-mounted display can be made compact and lightweight.
