    摘要: A compact high performance objective zoom lens system is disclosed that provides optimum optical performance over the entire zoom focal length range at focus distances from close to infinity. The system comprises, from object space to image space, one focusing objective lens group (comprising a focus lens group and a stationary lens group) and three zoom lens groups aligned on the optical axis. The focus lens group and the zoom lens groups are axially movable along the optical axis for focusing and zooming. In one embodiment, the system has a focal length zoom region from about 19 mm to 90 mm, an aperture of F/2.7 and substantially the same optical performance as high quality fixed objective lenses of the same range. The performance characteristics of this system makes it suitable for use with both film and electronic detector cameras.

    摘要: A zoom lens system is disclosed. The zoom lens system forms a final image of an object and a first intermediate real image between the object and the final image. The zoom lens system includes a first optical unit located between the object and the first intermediate real image. The first optical unit comprises at least one optical subunit which is moved to change the size (magnification) of the first intermediate real image. The zoom lens system also includes a second optical unit located between the first intermediate real image and the final image, at least a portion of which is moved to change the size (magnification) of the final image. The zoom lens system provides a wide zoom range of focal lengths with continuous zooming between the focal lengths and optional image stabilization.

    摘要: An anamorphic imaging system is disclosed which maximizes the use of available image area to minimize display magnification and image degradation due to display magnification, reduces the amount of anamorphic squeeze or stretch during photography to lower image degradation due to anamorphosis, and in film applications, utilizes a film frame that is only three perforations in height to reduce the amount of original film needed. The frame for either film or digital applications has an aspect ratio of approximately 16:9, is contained within the total available frame area of a three-perforation frame or digital imager, and is sized to maximize image area. In preferred embodiments, the image capture area is approximately 0.900 inches wide by approximately 0.506 inches tall.

    摘要: An afocal refractor telescope is formed by a fixed focus achromatic telephoto objective system (10) and a fixed focus eyepiece system (11) aligned on a common optical axis (12) and is arranged to provide an internal real image (13). The objective system (10) is formed by a primary lens element (D) and a secondary lens element (C) and the eyepiece system (11) has at least two lens elements (A, B). Each of the lens elements (A,B,C,D) of the telescope is made of a material having a useful spectral bandpass in the infrared wavelength region and has refractive surfaces (1,2,3,4,5,6,7,8) intercepting the optical axis (12), at least one of the refractive surfaces (7,8) of the primary objective lens element (D) being aspheric whereas the refractive surfaces (1,2,3,4,5,6) of the lens elements (A,B,C) are substantially spherical. The aspheric surface (7,8) possesses only a small degree of asphericity and is defined by an equation in which the third and higher order aspheric coefficients are zero. The secondary objective lens element (C) is negatively powered and has a refractive index equal to or lower than the refractive index of the primary objective lens element (D) which is positively powered and the arrangement is such that the telescope has an internal f-number in the airspace between the primary and secondary objective lens elements (D,C) which is less than 1.5.

    摘要: An afocal zoom refractor telescope 20 is formed by a variable magnification achromatic objective system 18 and a fixed focus eyepiece system 19 aligned on a common optical axis 17 and arranged to provide an internal real image I. The objective system 18 is formed by a primary lens element F and three other lens elements C,D,E, and the eyepiece system 19 is formed by two lens elements A,B. The six lens elements A-F are made of a material which has a useful spectral bandpass in the infrared wavelength region and all refractive surfaces (1-12) intercepting the optical axis 17 are substantially spherical. Objective lens system element E which is proximal the primary lens element F is color corrective with a V-value of not less than 120, negatively powered and with a lower refractive index than the remaining objective lens elements (C,D,F). Element E is fixedly coupled to the adjacent lens element D the pair being mounted for movement in a first locus along optical axis 17. Objective system lens element C which is proximal the eyepiece system 19 is mounted for movement in a second locus along the optical axis 17 and the movable elements E,D,C are simultaneously moved through the first and second loci so that the magnification of the telescope 20 can be varied between minimum and maximum values.

    摘要: The anamorphic objective lens systems (100LS) and methods for forming a set of anamorphic objective lens assemblies (100(i)) having different focal lengths (FLY) and that utilize a front anamorphic section (20) and a set of two or more non-anamorphic sections (50(i)). The non-anamorphic sections are optically matched to the front anamorphic section and their front ends (52) are configured to be easily attached to and detached from the back end (24) of the front anamorphic section to create the anamorphic objective lens assemblies having the different focal lengths. Because the anamorphic objective lens system uses only a single front anamorphic section and multiple non-anamorphic attachments, the cost of having multiple anamorphic objective lens assemblies is substantially reduced as compared to using individual anamorphic objective lenses for each of the desired focal lengths.

    摘要: A zoom lens including, along an optical axis and in order from an object space to an image space: first lens group with negative power; an aperture stop; a second lens group with positive power; a third lens group with positive power; and a fourth lens group. The second and third lens groups and the aperture stop are axially movable for zooming. At least one lens element in the first lens group is moveable to provide for focusing. The aperture stop moves independently of the lens groups during zooming and has a clear aperture that changes size during zooming.
