Patent number: 9207429Abstract: A compact camera lens composed of the following five lenses in this sequence proceeding from the object side: a first positive meniscus lens, wherein the concave surface of the first positive meniscus lens faces away from the object side; a second negative lens, wherein the object-side surface of the second negative lens is concave; a third positive lens, wherein the image-side surface of the third positive lens is convex; a fourth biconvex lens; and a fifth negative lens. The fourth biconvex lens and the fifth negative lens are in each case cemented with one another. The object-side surface of the third positive lens and the image-side surface of the fifth negative lens are of aspherical form. The objective is particularly robust, compact, has a large aperture and very good imaging characteristics. It is suitable for example as an objective of an exterior mirror replacement camera in the automotive field.Type: GrantFiled: June 15, 2012Date of Patent: December 8, 2015Inventors: Udo Schauss, Ralf Linn

Publication number: 20130107218Abstract: A system for stereoscopic cinema projection comprising at least one projector for projecting two images, one image for a first eye and one image for a second eye of a viewer, is proposed. The beam paths of the light emerging from the projector respectively run through a linear polarizer to a correspondingly assigned projection lens. After passing through the projection lens, the beam paths of the two images, which are different for the eyes of a viewer, run through a radial and respectively a tangential polarization filter and are simultaneously projected, with different polarization states, exactly one on top of the other onto a metallic projection wall. By means of a visual aid for both eyes of a viewer, the lenses of which are configured differently for each eye with a radial and respectively a tangential polarization filter, each partial image is made visible only for the first or left eye or the second or right eye (or vice versa) and the 3D impression is thus generated for the viewer.Type: ApplicationFiled: May 6, 2011Publication date: May 2, 2013Applicant: JOS.

Publication number: 20130107108Abstract: A camera module for imaging an object onto an image sensor and having at least two carrier plates, wherein a plurality of basic lenses are arranged on one carrier plate and a plurality of lens attachments are arranged on the second carrier plate. The carrier plates are arranged one above the other in two planes and are horizontally displaceable in order to position different basic lenses and vehicle attachments in the beam path and thus combine them with one another. One embodiment of the proposed solution comprises for example, six basic lenses and four telenegative lens attachments making it possible to realize 30 discretely switchable different focal lengths and to achieve a quasi-zoom having small dimensions.Type: ApplicationFiled: April 18, 2011Publication date: May 2, 2013Applicant: JOS.

Publication number: 20090303608Abstract: The invention relates to an optical system for the projection of digital image data comprising a fixed focal length lens and a pivotable focal length extender. The principal field of application of the invention is digital cinema projection, usually employing the wide-screen format 1.9:1 or the Cinemascope format 2.37:1 (width:height). For format changeover during projection, two different fixed focal lengths are realized by the insertion or removal of the focal length extender (1755) into the lens. The projection lens according to the invention has more favorable optical properties than the conventional zoom lenses, such as a minimal chromatic transverse aberration, high telecentricity, very small distortions and a small volume and weight.Type: ApplicationFiled: February 13, 2007Publication date: December 10, 2009Applicant: Jos.

Patent number: 6989937Abstract: A six-element cinema projection lens is described in front of which an aspherized plane-parallel plate is positioned on the screen side. This arrangement permits the cost-effective design of a cinema projection lens with a relative aperture of 1:1.7 having very good image-forming properties. The high relative aperture increases the light utilization and therefore leads to savings in energy and costs. Furthermore, the projection lens can be used both for cinemascope format and for widescreen format, the differences in brightness being compensated by a variable diaphragm.Type: GrantFiled: June 17, 2004Date of Patent: January 24, 2006Assignee: Jos.

Patent number: 6310731Abstract: An anastigmatic anamorphic lens, in particular for the projection of Cinemascope films, with a high aperture and an anamorphic factor of greater than 1.7. The anastigmatic anamorphic lens comprises a main objective with considerable positive astigmatism.
