摘要： A high-aperture wide-angle lens for digital image acquisition, comprising five lens elements, as viewed from the object side, i.e. from the left, a first, negative meniscus lens element, a second, positive lens element, a third, positive lens element, a fourth, negative lens element and a fifth, positive meniscus lens element. A diaphragm is arranged between the second lens element and the third lens element. At least three surfaces upstream of the diaphragm and three surfaces downstream of the diaphragm are embodied as aspherical surface. However, further surfaces can also have an aspherical design. On account of its extremely compact design and its outstanding optical properties, the proposed high-aperture wide-angle lens is suitable as an interchangeable lens for so-called “hybrid cameras”.

摘要： 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.

摘要： An imaging system for imaging an object onto an image sensor, and which has a front side facing the object and a rear side facing away from the object, the rear side being arranged behind the front side as viewed from the object. Furthermore, the imaging system has a light entrance device at the front side through which light coming from the object can enter into the imaging system. In this case, the light traverses the beam path between object and image sensor. At least one first and one second optical element are likewise present and are arranged at the rear side in such a way that they can influence the beam path. The light entrance device has an electrically switchable liquid crystal element which deflects the beam path at at least one first angle and a second angle which is different from the first angle depending on the electrical switching state. A discretely switchable focal length change is realized by this electrically effected change in the beam path.

摘要： 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.

摘要： To indicate the position of a gauge, measuring rod or similar implement, a scale carrier mechanically coupled with that implement bears two sets of light-transmissive (i.e. transparent or reflective) areas aligned in the direction of displacement, the areas of at least one set being numerals or other distinctively shaped characters representing different measuring positions. In each measuring position an area of one set is aligned with an associated area of the other set in a common optical path including one or more ray-transposing reflectors so positioned that the images of the two areas, as focused by an objective in that path upon a display surface, move in opposite directions upon a displacement of the scale carrier. In a simple case, the areas of one set are small windows or mirrors acting as localized light emitters; for greater precision, they are the laterally reversed counterparts of the characters represented by the areas of the other set.

摘要： A clock with two coaxial transparent or translucent disks bearing hour and minute digits, respectively, has a screen onto which the instantaneous time is projected by an optical system including an objective in line with overlapping peripheral zones of the two disks. The digits of one disk are carried on an annular ridge of its peripheral zone received in an annular depression of the other disk so that the two sets of digits lie in the same plane, the objective being focused upon that plane.
