Abstract: The invention provides methods and apparatus comprising a multi-wavelength laser source that uses a single unfocused pulse of a low intensity but high power laser over a large sample area to collect Raman scattered collimated light, which is then Rayleigh filtered and focused using a singlet lens into a stacked fiber bundle connected to a customized spectrograph, which separates the individual spectra from the scattered wavelengths using a hybrid diffraction grating for collection onto spectra-specific sections of an array photodetector to measure spectral intensity and thereby identify one or more compounds in the sample.

The ribbon element includes a first light reflector including a plurality of first light reflection surfaces configured to be translated in an out-of-plane direction, and a second light reflector including a plurality of second light reflection surfaces that are fixed. The circuitry supplies a drive signal to the ribbon element in such a manner that a change of a displacement amount difference between the first light reflection surfaces and the second light reflection surfaces corresponds to a predetermined frequency; and acquires the light quantity data detected by the light detection element at a predetermined sampling frequency.

Abstract: A method and apparatus for actuating an acousto-optical component for manipulating light passing therethrough, in particular for manipulating the illumination and/or detection light in the beam path of a microscope, preferably a laser scanning microscope, where the illumination and/or detection wavelength is adjusted by means of at least one frequency generator connected to the acousto-optical component and controlling the manipulation, the frequency generator generates a signal which generates a spectral spread for the intensity distribution of the wavelength of the illumination and/or detection light for ensuring a temperature-independent manipulation. Actuation is effected by two or more actuation signals in such a way that two or more overlapping and/or superposing main lobes of the transfer function of the acousto-optical component or main maxima are generated.

Abstract: Aspects of blending data detected by a monochromator over multiple wavelength ranges is described herein. In one embodiment, the monochromator includes a diffraction grating, a grating drive motor that rotates the diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that blends data values from the first reflection and data values from the second reflection together to provide a spectrum of combined data values. By blending data detected over multiple ranges, measurements of relatively high precision and quality can be provided over a wider spectral range.

Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus based on a high repetition rate pulsed laser. The laser produces a train of laser pulses at a high repetition rate in the kHz or even higher range. When the laser beam hits the sample, it generates several thousands of micro-plasmas per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasmas. By adjusting the integration time of the spectrometer to cover a plurality of periods of the laser pulse train, the spectrometer integrates the LIBS signal produced by this plurality of laser pulses. Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the limit of detection (LOD). In addition, the influence of pulse to pulse variation of the laser is minimized since the obtained LIBS spectrum is the spectrum of a plurality of micro-plasmas produced by a plurality of laser pulses. The high repetition rate laser also makes it possible for fast scanning the laser beam over the sample surface such that an average spectrum of the sample is collected to overcome the sample non-uniformity issue or for performing spectral imaging of the sample by correlating the obtained LIBS spectrum with the position of the scanning laser beam.

Abstract: Implementations of the present disclosure relate to a plasma chamber having an optical device for measuring emission intensity of plasma species. In one implementation, the plasma chamber includes a chamber body defining a substrate processing region therein, the chamber body having a sidewall, a viewing window disposed in the sidewall, and a plasma monitoring device coupled to the viewing window. The plasma monitoring device includes an objective lens and an aperture member having a pinhole, wherein the aperture member is movable relative to the objective lens by an actuator to adjust the focal point in the plasma using principles of optics, allowing only the light rays from the focal point in the plasma to reach the pinhole. The plasma monitoring device therefore enables an existing OES (coupled to the plasma monitoring device through an optical fiber) to monitor emission intensity of the species at any specific locations of the plasma.

Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.
