摘要： A wide-angle zoom lens with as few as two plastic elements codes the wavefront produced by the imaging system such that the imaging system is substantially invariant to aberrations related to misfocus. Signal processing is used to decode the wavefront to form the final image. A first type of zoom lens configuration uses as few as two lens elements. In this type, image processing may be modified to take into account the positioning of the lenses.

摘要： The invention relates to an optical system or apparatus such as a lens system capable of focus control and a variable-focus lens, which has reduced power consumptions, ensures noiseless operation and fast response and contributes to cost reductions for the reason of simplified structure. Specifically, the invention provides an optical apparatus comprising an element 409 having variable optical properties and an image plane 612. To correct the optical apparatus for movement of the image-formation surface of an optical system 614 in association with a change in the element 409 having variable optical properties, the image plane 612 is placed in the range of movement of the image-formation surface in association with the change in the element having variable optical properties.

摘要： A two position variable focal length lens is provided. The variable focal length lens includes a common lens element moveably positioned on an optical axis; a wide angle lens element moveable between a first location removed from the optical axis and a first position on the optical axis on an image side of the common lens element; and a telephoto lens element moveable between a second location removed from the optical axis and a second position on the optical axis on the image side of the common lens element. A magnification ratio change is effected by moving the common lens element along the optical axis and switching between the wide angle lens element located at the first position on the optical axis and the telephoto lens element located at the second position on the optical axis.

摘要： A projection zoom lens system of the present invention having telecentric incident side is suitable for a projector apparatus using LCD or DMD with prism. The projection zoom lens system of this invention comprises five lens groups having, from the screen side, negative, positive, positive, negative and positive power. In addition to this arrangement, since the lens located closest to the screen is a screen side convex negative meniscus lens, wide-angled and bright zoom lens system can be realized. Further, by designing the distribution of power of the first lens group located closest to the screen, the projection zoom lens provides further improved aberration correction. As the condition for realizing the aforementioned projection zoom lens system, it is preferable that a focal length f1 of the first lens group and a focal length at a wide-angle end fw satisfy the following condition:-1.9

摘要： Accessories are disclosed for use with a laser tool which may or may not be self-leveling. The accessories include one or more diffraction elements, effective to receive the incoming beam and produce a plane of diverging laser beams. In preferred embodiments the diffraction elements are self-leveling. When the diverging beams are directed against a surface such as a floor, wall or ceiling, a series of discrete spots define a visible reference line useful in construction layout. The spots themselves may each locate the position of a fastener to be installed, for example, by giving the approximately correct spacing for reference of the user. In another embodiment, lenticular arrays are used to create beams which diverge in a plane and overlie one another to form a visible reference line on a wall or other surface. The line preferably is plumb or level and in one embodiment the user can select among two or more arrays to form a plumb or level line of selected length.

摘要： A zoom objective for a photographic printer has a housing which accommodates two groups of lenses. One group is fixed and the other group is shiftable along the optical axis of the objective to change the magnification. The housing is externally threaded and meshes with an internally threaded magnification ring which surrounds the housing and serves to move the shiftable lens group. A clamping ring circumscribes the housing on either side of the magnification ring, and the clamping rings constitute abutments for the magnification ring. The clamping rings are adjustable along the optical axis of the objective. The housing is further surrounded by an internally threaded focusing ring which is in mesh with the housing and is provided with mounting elements for mounting the objective in a printer. The position of the housing in the printer can be varied by rotating the housing and the focusing ring relative to one another. This allows the objective to be focused following a change in magnification. Two additional clamping rings circumscribe the housing with one of the additional clamping rings being disposed on either side of the focusing ring. The additional clamping rings, which are again adjustable along the optical axis of the objective, function as abutments for the focusing ring.
