Abstract: The present disclosure resides in a spectrometer arrangement including a first dispersing element for spectral separation of radiation in a main dispersion direction, and a second dispersing element for spectral separation of radiation in a cross-dispersion direction, which is at an angle to the main dispersion direction, so that a two-dimensional spectrum is producible. The spectrometer arrangement also includes a collimating optics, which directs collimated radiation to the first and/or second dispersing element, a camera optics, which images a two-dimensional spectrum in an image plane, a two-dimensional detector for detecting the two-dimensional spectrum in the image plane, and an off-axis section of a rotationally symmetric, refractive element, which is arranged between the camera optics and the detector. The present disclosure resides likewise in an optical module comprising such a spectrometer arrangement.

Abstract: The present disclosure discloses a spectrometer arrangement including an entrance-slit group including a slit wheel and a slit mask for introducing radiation into and for limiting the optical field of the spectrometer arrangement, a first dispersive element for spectrally decomposing the radiation in a main dispersion direction, and a second dispersive element for spectrally decomposing the radiation in a transverse dispersion direction that forms an angle with the main dispersion direction to yield a two-dimensional spectrum. The slit wheel is mounted rotatably about an axis of rotation and has a falcate opening having a width that changes depending on the angle. The slit mask includes an opening that is longer than a largest width of the falcate opening such that radiation radiates through the falcate opening of the slit wheel and the opening of the slit mask. The present disclosure further includes a corresponding method and an optical component group.

Abstract: A sheet-fed printing press includes a printing cylinder and a high-precision sensor system for monitoring a sheet run in the area of the printing cylinder. At least one gage, which is mounted on the printing cylinder, can be detected by the sensor system. It is particularly advantageous if the sensor system is configured to be self-calibrating. A method for calibrating a sensor system and a method for aligning a sensor system are also provided.

Abstract: A cooling system is provided for a thermoelectric power generator and that is arranged in an exhaust gas line of an internal combustion engine for generating electric power while utilizing thermal energy of the exhaust gas. The thermoelectric power generator has its own coolant circuit, which also serves to raise the temperature of the components of the internal combustion engine, the chassis, and/or the transmission or serves to heat the passenger compartment. This offers the added utility gained from a faster temperature rise of transmission lubricants and lubricants of the internal combustion engine, as well as from heating the passenger compartment and the rear axle differential and, thus, offers a reduction of carbon dioxide emissions (CO2).

Abstract: Described and claimed are apparatuses and systems for surface cleaning comprising a pump and an applicator connected to the pump through which one or more cleaning agents can be applied to the surface at an operating pressure that is about 600 PSI or less and an operating flow rate that is about 1 gal/min or less.
