Abstract: An infrared Raman device is capable of switching and performing Raman measurement and first infrared measurement on a sample. The infrared Raman device includes an objective lens for Raman measurement; a first observation lens for infrared measurement; a laser light source that generates laser light; a first infrared light source that generates first infrared light; and a mirror. The mirror is disposed at time of the Raman measurement to reflect the laser light to cause the laser light to pass through the objective lens for Raman measurement and reflect Raman light generated from the sample by the laser light that passes through the objective lens for Raman measurement and radiated to the sample. The Raman light passes back through the objective lens for Raman measurement.

Abstract: A measurement system may comprise an actively illuminated camera system, in some embodiments coupled to a time-of-flight sensor or an array of laser diodes beam split into a plurality of spatially separated lights. The camera system may capture two or three dimensional images, and the light source may comprise semiconductor diodes, such as light emitting diodes. The system includes a processor coupled to non-transitory computer readable medium and configured to use artificial intelligence to make one or more decisions. The processing may also involve artificial intelligence or machine learning techniques to analyze anomalous occurrences, or generative artificial intelligence to interface with a user or improve the performance of camera-based systems. Algorithms may also be used to improve the performance of generative artificial intelligence processing. The camera output may be fused with data from other sensors, and the camera may also capture information about the pose or gestures of a user.

Abstract: The invention relates to a thermal radiation source which comprises a housing, an electrically operated radiation element arranged in the housing and an exit window through which radiation emitted by the radiation element is emitted from the housing, and to two methods for measuring the temperature of an exit window of the thermal radiation source and/or the radiant flux through an exit window of radiation emitted by the thermal radiation source. The problem of developing a possibility of being able to measure the radiant flux emitted by a thermal radiation source and/or the surface temperature of the exit window is solved by virtue of the exit window having a pass region, a contacting region and a measurement region, the measurement region and the pass region being formed separately from one another and/or with a partial overlap, with a temperature and/or radiation sensor being arranged within the measurement region of the exit window, the temperature and/or radiation sensor being electrically contacted via the contacting region.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: The invention relates to a modulatable infrared emitter comprising a MEMS heating element and an actuator, wherein the actuator triggers shape and/or structure changes of the MEMS heating element. Said change in shape and/or structure of the MEMS heating element may vary the ratio of the emitting area to the total area, thereby producing a change in intensity of the emitted infrared beam. The invention further relates to a manufacturing method for the infrared emitter, a method for modulated emission of infrared radiation using the infrared emitter, and preferred uses of the infrared emitter. In further preferred aspects the invention relates to a system comprising the infrared emitter and a control device for regulating the actuator.

Abstract: A device may receive information identifying results of a set of spectroscopic measurements of a training set of known samples and a validation set of known samples. The device may generate a classification model based on the information identifying the results of the set of spectroscopic measurements, wherein the classification model includes at least one class relating to a material of interest for a spectroscopic determination, and wherein the classification model includes a no-match class relating to at least one of at least one material that is not of interest or a baseline spectroscopic measurement. The device may receive information identifying a particular result of a particular spectroscopic measurement of an unknown sample. The device may determine whether the unknown sample is included in the no-match class using the classification model. The device may provide output indicating whether the unknown sample is included in the no-match class.
