    Abstract: A monitor for particles of various materials which counts the number of the particles on real-time and in situ basis. The monitor comprises a unit for illuminating an object to be inspected with an illumination light beam of a predetermined cross-sectional area, a unit for detecting a change in optical mode of the illumination light beam caused by the particles being contained in the inspected object and illuminated with the illumination light beam, the illuminating and detecting units being of a unitary structure, and a unit for counting an amount of the particles contained in the inspected object by using a change in intensity of an optically mode changed light beam.

    Abstract: The present disclosure relates to the field of optical systems, in particular to an atomic emission spectrometer. The envisaged multi-scan optical system (100) is compact and stable. The system comprises an excitation source (104), a hydra fiber cable (106), a wavelength selector (103), a dispersive optical element (101), and a detector (102). The excitation source is configured to emit composite light. The hydra fiber cable has a head and a plurality of tentacles, and is configured to receive the composite light via a second lens. The plurality of tentacles is configured to emit the composite light towards the wavelength selector which includes a plurality of optical slits (s1 - s8) and a plurality of shutters. The wavelength selector is configured to selectively collect and filter the composite light directed by a first lens and the plurality of tentacles by means of the plurality of shutters. The detector is configured to detect the plurality of spectral line scans reflected by the dispersive optical element for spectrometric analysis.

    Abstract: An analytical instrument may have multiple distinct channels. Such may include one or more illumination sources and sensors. Illumination may be delivered to specific locations of a specimen holder, and returned illumination may be delivered to specific locations of a sensor array. Illumination may first pass a specimen, and a mirror or reflector may then return the illumination past the specimen. Optical splitters may be employed to couple pairs of fiber optics proximate a specimen holder. Such channels may further include a plurality of illumination sources positioned on one side of a specimen holder and a plurality of sensors on the other side. The plurality of sensor may capture image of a specimen and a spectrophotometer may concurrently scan the specimen. A plurality of specimens may be imaged and scanned in a single pass of a plurality of passes. Spherical or ball lenses may be placed in an optical path of the illumination to achieve a desired illumination pattern.
