| 20120033228 | METHOD FOR ZERO-CONTACT MEASUREMENT OF TOPOGRAPHY" - A method for zero-contact measurement of the topography of a spherically or aspherically curved air-glass surface of an optical lens or lens combination, distinguished in that the surface (S | 02-09-2012 |
| 20090303608 | OPTICAL SYSTEM FOR DIGITAL CINEMA PROJECTION - 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 ( | 12-10-2009 |
| 20090135499 | MACRO OBJECTIVE - A description is given of a macro objective (M) with a corrective compensation of aberrations (Continuous Aberration Suppression; CAS). The macro objective has a first positive optical subassembly (A), a second nearly afocal optical subassembly (B), a stop (APE), a third nearly afocal optical subassembly (B′) and a fourth positive optical subassembly (A′). The third optical subassembly (B′) and the fourth positive optical subassembly (A′) are designed with mirror symmetry relative to the optical subassemblies (A, B) upstream of the stop (APE). The nearly afocal optical subassemblies (B, B′) are displaced jointly inside the macro objective (M) along the optical axis (OA) with the aid of mechanical means in conjunction with linear magnifications of β′≠−1. As a result, the macro objective (M) achieves outstanding imaging properties both over a wide range of linear magnifications (β′=−2.0 to −0.5) and over a wide wavelength spectrum. | 05-28-2009 |
