Abstract: The present invention provides a spectroscopic system as well as a method of autonomous tuning of a spectroscopic system and a corresponding computer program product. By detecting the position of return radiation in a transverse plane of an aperture of a spectroscopic analysis unit, a control signal can be generated that allows to drive servo driven translation or tilting stages of optical components. In this way a transverse misalignment of a spectroscopic system can be effectively detected. Generally, a plurality of different detection schemes are realizable allowing for an autonomous tuning of the spectroscopic system and for autonomous elimination of misalignment of a spectroscopic system.

Abstract: A catoptric, wide-angle optical system includes at least three mirrors. Only the last mirror on the beam path (22) has a positive optical power and all other mirrors have negative optical power. The sum of the optical powers of the mirrors is zero. An external posterior aperture stop (35) is located on the beam path (22) between the last mirror and the image plane (24). The back focal length of the optical system (20) is equal to or greater than an effective focal length of the optical system (20). The field of view is large, and typically at least 30-40 degrees in one plane.

Abstract: Proposed is a light sensor (1), comprising at least one wavelength selective photo-detector (10), a lens (20) and an aperture (30).The wavelength selective photo-detector allows detecting light within a predefined wavelength range falling on the sensor. The lens project light on the photo-detector and the aperture defines a field of view of the light sensor. The photo-detector (10), the lens (20), and the aperture (30) are arranged in a telecentric configuration. Advantageously, this allows light to impinge on the wavelength selective photo-detector within a predefined range of angles irrespective of the direction of the light incident on the aperture, thus removing the angle dependent response of the wavelength selective photo-detector.

Abstract: A method and system for accurate and precise representation of color for still and moving images, particularly sequences of digitized color images. Spectral and/or extended dynamic range information is retained as images are captured, processed, and presented during color adjustment. Using this extra spectral information, various methodologies for further presenting or processing the color within these images can be optimized. Presentation-device independence is achieved not by attempting to discover a device-independent intermediate representation, but rather by deferring the binding and mapping of color representation onto a presentation device until its actual use.

Abstract: The invention relates to an optical arrangement, particularly for the use as a main beam splitter and/or beam combiner in a microscope, wherein one or several light rays (11, 12, 15, L1, L2, L3) can be coupled into and one of the coupled light rays (11, 12, 15, L1, L2, L3) can be uncoupled again after passage of the optical arrangement (1, 11). The optical arrangement is characterized in regard to as much a free influenceability as possible of the uncoupled light ray, by having a controllable microstructured element (5), for example a digital micro mirror device (DMD), arranged in the coupled light rays (11, 12, 15, L1, L2, L3), making it possible for beam paths within the optical arrangement (1, 1') to be controllable. Thus the uncoupled light ray/s is/are controllable and/or can be influenced.

Abstract: In a spectrometer, preferably in a spectrometric microscope, light from a specimen is collected at a collector objective element and delivered to a camera element, which in turn provides the light to a photosensitive detector. A focal plane is provided between the collector objective element and the camera element, and one or more aperture arrays may be situated in the focal plane to restrict the detector's field of view of the specimen to the areas within the apertures. By utilizing aperture arrays with apertures of different sizes and shapes, the spatial resolution of the spectrometer readings may be varied without the need to vary the optics of the spectrometer. As a result, if the optics are optimized to minimize vignetting, spatial resolution may be varied without adverse increases in vignetting.
