Abstract: A method for calibrating a medical imaging device is provided. The medical imaging device may be an endoscope system or an exoscope system. The medical imaging device includes an optical system with optics and an imaging sensor for capturing an image of a viewing region, and image information of the image being subject to a spectral deviation as a result of an internal and/or external influence, as a result of the optical system, lighting and/or an ambient condition, said method having multiple steps. A medical imaging device, in particular a medical endoscope or a medical exoscope incorporating the method is also provided.

Abstract: An endoscopic and/or exoscopic imaging device for spectral, in particular multispectral and/or hyperspectral, imaging for an endoscope, microscope and/or an exoscope, comprising at least one shaft and comprising at least one imaging channel situated at least in part in the shaft, which imaging channel comprises at least one first imaging branch that has having at least one first spectrally selective beam splitter that spectrally selectively splits an optical image of an original spectral range into at least one first partial spectral image of a first spectral range and at least one further first partial spectral image of a further first spectral range, wherein the first spectral range is different from the further first spectral range, and the first imaging branch comprises a first image sensor, at least for capturing the first partial spectral image, and the first imaging branch comprises at least one first relay lens for relaying the further first partial image.

Abstract: An endoscope includes a shaft having a distal end, an optical imaging device at the distal end of the shaft for producing a real image of an object observed by means of the endoscope and at least one of an image transfer device for transmitting the real image and an image sensor for capturing the real image. The imaging device has curved light-refracting interfaces, which are tilted in relation to one another.

Abstract: This invention relates to a drive end of a roller for producing and/or treating a material web, in particular a paper web or paperboard web, the drive end including a hollow-cylinder-shaped roller casing and a drive journal which is connected to the roller casing in order to drive said casing. The drive journal stands in a driven connection to a drive unit or can be switched into such a driven connection. The drive journal has an axial bore in the direction of the axis of rotation of the roller, said bore extending from an outer end face of the drive journal to an inner end face of the drive journal inside the roller casing. Provision is made on the outer end face of the drive journal for a drive flange by way of which a drive torque can be transmitted onto the drive journal.

Abstract: A roller bearing includes at least one inner ring and at least one outer ring, with at least one of the inner and outer rings being comprised of at least four segments. In addition, at least one of the segments is provided with a mechanism for moving the segment in the radial direction. This radial setting mechanism can be in the form of a cam that functions between the segment and a housing accommodating the segment.
