Compact camera lens of highest imaging quality for a camera with full-framed sensor

A camera lens, e.g., for a full-frame camera, may have a first compound lens leading on the object side, a second compound lens following the first compound lens, a third compound lens that terminates on the sensor side and follows the second compound lens, and an aperture stop arranged between the first compound lens and the second compound lens. The first compound lens may have a converging refractive power. ... Carl Zeiss Ag

Cmos image sensor with shared sensing node

A cmos image sensor has a pixel array provided with a plurality of unit pixels arranged in a matrix shape of rows and columns. Each of the unit pixels includes a photocharge generation means for generating photocharges by absorbing an external light; and a sensing node for receiving the photocharges transferred from the photocharge generation means, wherein the sensing node of the unit pixel in a previous scan line is shared with a sensing node of a unit pixel in a current scan line in response to a line select signal of the current line.. ... Carl Zeiss Ag

Illumination device for a projector comprising a light modulator

An illumination device for a light modulated projector includes a first and a second colour wheel. A first filter surface of the first colour wheel comprises at least three first surface sections arranged one behind the other, which protrude into an illumination beam path of the illumination device successively on rotation and in each case convey illumination radiation of a different partial range of the visible wavelength range. ... Carl Zeiss Ag

Display device which can be placed on the head of a user

There is provided a display device with a holder that can be fitted on the head of a user and a first imaging optical system secured to the holder, which is formed to image an image generated in an image plane as a virtual image in such a way that, when the holder is fitted on his head, the user can perceive it with a first eye, wherein the first imaging optical system includes, as imaging element, precisely one first lens with a first and a second boundary surface, wherein the two boundary surfaces are each aspherically curved.. . ... Carl Zeiss Ag

Catadioptric eyepiece system, eyepiece system and optical system

Catadioptric eyepiece system having an exit pupil, comprising a display having a surface disposed in an object plane; optics providing a beam path from the display to the exit pupil and being configured to image a portion of the object plane into an intermediate image formed in a curved intermediate image plane; wherein the optics comprise: a lens system of positive optical power comprising at least one lens, wherein the lens system is disposed in the beam path downstream of the display and upstream of the intermediate image; a concave first mirror disposed in the beam path downstream of the intermediate image and upstream of the exit pupil; and a first beam splitter disposed in the beam path between the lens system and the first mirror and between the first mirror and the exit pupil.. . ... Carl Zeiss Ag

Objective lens for a photography or film camera and method for selective damping of specific spatial frequency ranges of the modulation transfer function of such an objective lens

A lens for a still or film camera includes a first and second lens-element arrangement, and a wavefront manipulator. The first and second lens-element arrangement are arranged spaced mutually apart along an optical axis of the lens such that an interstice is present therebetween. ... Carl Zeiss Ag

Light-scanning microscope with simplified optical system, more particularly with variable pupil position

A light-scanning microscope including a scan optics for generating a pupil plane conjugate to the pupil plane of the microscope objective, and a variably adjustable beam deflection unit in the conjugate pupil plane. An intermediate image lies between the microscope objective and the scan optics. ... Carl Zeiss Ag

Projector for projecting images

Each modulator of an image projector includes multiple pixels arranged in rows and columns, switchable independently of each other into a first state, in which light incident on them is used to generate an image, and into a second state, in which light incident on them is not used to generate an image. At least one first pixel is assigned to each second pixel such that the imaging optical system a) strikes the second pixel with light from the respective assigned first pixel when the assigned first pixel is switched into the first state, in order to illuminate the second pixel actively, and b) does not strike the second pixel it with light from the respective assigned first pixel when the assigned first pixel is switched into the second state, in order not to illuminate the second pixel actively. ... Carl Zeiss Ag

Optical system for producing lithographic structures

An optical system for producing lithographic structures is disclosed. Also disclosed is a method for determining relative coordinates of a position of a writing field relative to a position of a preview field in such an optical system, and a method for producing lithographic structures using such an optical system.. ... Carl Zeiss Ag

Functionally integrated laser scanning microscope

A functionally integrated laser scanning microscope for scanning a sample with laser illumination, selectably in a confocal, line or wide-field operating mode, comprising a laser light source, an illumination and detection beam path, a detection device and at least one objective, wherein the illumination and detection beam path has optical means for the configuration of the laser illumination, at least one scanner for scanning the sample with the laser illumination, and a beam splitter for separating illumination and detection light, and controllable optical elements for changing the beam guiding depending on the operating mode selected in each case.. . ... Carl Zeiss Ag

Display device for demonstrating optical properties of eyeglasses

A display device with a retaining device is disclosed, which can be placed on the head of a user. The display device contains a first image generator, which is secured or can be secured to the retaining device, and a first optical imaging system which is secured to the retaining device and which is designed to image an image generated on a first image plane (e) by the first image generator such that the user can perceive the image with a first eye (la) when the retaining device is placed on the head of the user. ... Carl Zeiss Ag

Microscopic examination of an object using a sequence of optical microscopy and particle beam microscopy

A slide system for optical microscopy using immersion fluid including a cover glass having a first refractive index and a transparent film having a second refractive index. The second refractive index of the transparent film is matched to the first refractive index of the cover glass. ... Carl Zeiss Ag
