    摘要: The optical system disclosed in this specification is a variable power optical system for enlarging and projecting a reduction side object onto an enlargement side image plane, or reducing and projecting an enlargement side object onto a reduction side image plane. This variable power optical system includes a first optical component having a reflecting curved surface, and a second optical component disposed more toward the reduction side than the first optical component. The second optical component has a plurality of movable lens units, and the variable power optical system effects a variable power operation by movement of the plurality of lens units. If ray was traced from the reduction side toward the enlargement side, the second optical component forms an image of a reduction side conjugate point on the enlargment side than an optical surface of the first optical component that is most adjacent to the reduction side. Thereby, there is realized a variable power optical system of a compact construction in which a desired variable power ratio is obtained and yet the occurrence of various aberrations including chromatic aberration of magnification is suppressed.

    摘要: A lens has a lens body (1), reinforcing extensions (3a, 3b) and a clear aperture (9) surrounded on top and bottom by lens body. The lens is suitable for spot scanning. The lens is made of a water absorbing material, such as most polymers, particularly acrylate polymers. Aluminum sheets as vapor barriers are attached on each side of the lens body. This results in excellent resistance to change or distortion in high humidity environments.

    摘要: A luminous flux, from one conjugate surface (A), having an opening angle of at least 10null sequentially passes through a first optical system (30) having a luminous flux convergent action in the vicinity of its reference axis and a second optical system (31) having a luminous flux divergent action in the vicinity of its reference axis, and converges on another conjugate surface (B). A specific condition is given to the converging distance of each converging point at a luminous flux section including a principal ray according to the passing position of the luminous flux through the first optical system (30) to thereby implement an oblique-incident optical system having a half angle of at least 60null and a comparatively simple structure irrespective of a type of an optical element used.
