Abstract:
Rolling bearings comprise a plurality of rolling bodies which during operation roll off on raceways. In order to reduce friction during rolling, it is customary to supply the rolling bearings with a lubricant. However, the quality of the lubricant can deteriorate during operation due to long-term stress, aging, or thermal influences, or get lost in gaps etc. The problem addressed by the invention is that of proposing a sensor device, which can be operated in a functionally reliable manner. This problem is solved by a sensor device (1) for monitoring the state of a lubricant in a lubricant chamber (12), comprising a transmitter platform (9), wherein on the transmitter platform (9), a plurality of diode units (14) are arranged, having a measuring-window unit (5), wherein the measuring-window unit (5) is arranged between a measuring chamber (13) and the lubricant chamber (12), having a receiving unit (16), wherein at least one of the diode units (14) comprises a die (22) and a plastic dome (25). The plastic dome (25) and the die (22) are connected by way of a contact surface (26), wherein the contact surface (26) is arranged on an upper side of the die (22).
Abstract:
An imaging assembly and processing system that includes a sample platform having a target region which can hold a sample, where the sample can be marked with fluorescent or phosphorescent markers. The imaging assembly can have an excitation light module proximate to the sample platform that emits light to excite the markers, and a lens module positioned to receive emission light from excited markers in target region. At least one series filter assembly or interference filter can be arranged in front of, behind, or both in front of and behind the lens module. The assembly includes a light sensor and a processor and imaging module configured to process data captured by the light sensor. Images of the sample are generated based on the emission light from the sample that transmit through and are filtered by the lens assembly and series filter assembly or interference filter.

A catadioptric optical system (1200) operates in a wide spectral range. In an embodiment, the catadioptric optical system (1200) includes a first reflective surface (57) positioned and configured to reflect radiation; a second reflective surface (58) positioned and configured to reflect radiation reflected from the first reflective surface as a collimated beam, the second reflective surface having an aperture to allow transmission of radiation through the second reflective surface; and a channel structure (1380) extending from the aperture toward the first reflective surface and having an outlet (1330), between the first reflective surface and the second reflective surface, to supply radiation to the first reflective surface.
Abstract:
Described is a sensor that makes it possible to determine visual range and rain cover simultaneously. Thus, light is coupled into the pane in such a way that part of the light is reflected and part leaves the pane and is dispersed outside the pane. The rain cover is determined from the reflected part and the distance is determined from the dispersed part that comes back to the pane, the two parts being detected using an outcoupling mechanism and a light receiver.
Abstract:
A capillary flowcell (12) includes an optical axis, the optical axis being defined by, in sequential order, (a) a first (entrance) aperture (14), (b) a first lens (26), (c) a capillary tube (16) having its long axis centered across the optical axis, and (d) a second lens (28). The first lens (26) focuses electromagnetic radiation from the entrance aperture (14), passes through the inner diameter of capillary tube (16) thus maximizing the signal generated by the analyte within the capillary tube (16). The second lens (28) focuses electromagnetic radiation which has passed through the capillary tube (16).
