Abstract: An analysis (e.g., LIBS) system includes a source of radiation, an optical emission path for the radiation from the source of radiation to a sample, and an optical detection path for photons emitted by the sample. A detector fiber bundle transmits photons to the spectrometer subsystem. At least one fiber of the fiber bundle is connected to an illumination source (e.g., an LED) for directing light via at least a portion of the detection path in a reverse direction to the sample for aligning, sample presence detection, localizing, and/or focusing based on analysis of the resulting illumination spot on the sample.

Abstract: A chromatic confocal distance sensor has a housing in which a polychromatic light source, imaging optics having a longitudinal chromatic aberration, a spectrometer and a planar beam splitter surface are arranged. These lie in the light path of the measurement light between the light source and the imaging optics and between the imaging optics and the spectrometer. A first diaphragm is arranged in the light path between the light source and the beam splitter surface, and a second diaphragm is arranged in the light path between the beam splitter surface and the spectrometer. The diaphragms are arranged mirror-symmetrically with respect to the beam splitter surface. The measurement light propagates as a free beam inside the housing. The beam splitter surface, the first diaphragm and the second diaphragm are fastened together on a carrier which has an isotropic thermal expansion coefficient. This way, temperature changes cannot significantly affect the measurement accuracy.

Abstract: A cavity-enhanced absorption spectroscopy instrument has an optical cavity with two or more cavity mirrors, one mirror of which having a hole or other aperture for injecting a light beam, and the same or another mirror of which being partially transmissive to allow exit of light to a detector. A spherical-spherical configuration with at least one astigmatic mirror or a spherical-cylindrical configuration where the spherical mirror could also be astigmatic prevents a reentrant condition wherein the injected beam would prematurely exit the cavity through the aperture. This combination substantially increases the number of passes of the injected beam through a sample volume for sensitive detection of chemical species even in less than ideal conditions including low power laser or LED sources, poor mirror reflectivity or detector noise at the wavelengths of interest, or cavity alignment issues such as vibration or temperature and pressure changes.

Abstract: A detector apparatus is provided and includes a collector having access to a sample of a gaseous fluid and a tester coupled to and disposed remotely from the collector. The tester includes a test chamber into which a sample is directed from the collector, an excitation element to excite the sample in the test chamber and a spectrum analyzing device coupled to the test chamber to analyze the excited sample for evidence of a concentration of particles of interest in the gaseous fluid exceeding a threshold concentration. The threshold concentration is defined in accordance with a type of the particles of interest and a residence time of the sample.

Abstract: The present system provides a sensor clip system that can be clipped to luminaires of a plurality of shapes and sizes and method of using the sensor clip. Some of the sensors are upward looking (into the luminaire) while others are downward looking (away from the luminaire); and thus face in substantially opposite directions. The sensor clip is adjustable in one, two or three dimensions to be able to easily fit with different sized and shaped luminaires, such that the upward looking sensors may face the incoming light and downward looking sensors face away from the light. The sensor clip system may also provide attenuation of the luminous intensity of the emitted light coming out of the luminaires and extends the longevity and usability of the embedded sensor.

Abstract: A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).

Abstract: A non-power-driven photometer is provided, the photometer comprising: a body; and multiple narrow angle photoreceivers (narrow angle probes) formed in the body, wherein the multiple narrow angle probes receive light in the atmosphere, which is incident over a range of different azimuth angles, and allow the characteristics of the atmosphere to be analyzed with reference to the relationship between the received light and the azimuth angle of the narrow angle probe corresponding to the received light. According to the present invention, since the photometer is driven without being supplied with power, light intensity measurement can be performed in a short time. Further, since light intensity measurement can be performed with no movement or only a short-distance movement of a vehicle or airplane equipped with the photometer, the problem of errors caused by differences in the time and location of measurement can be prevented.
