Abstract: The present invention is enclosed in the area of machine learning, in particular machine learning for the analysis of High or Super-resolution spectroscopic data, which typically comprises analysis of highly complex samples/mixtures of substances and/or data with low resolution, for instance Laser-Induced Breakdown Spectroscopy (LIBS). It is an object of the present invention a method of computational self-learning for characterization of one or more constituents in a sample, from electromagnetic spectral information of such sample, which changes the paradigm associated with prior art methods, by using only sub-optical spectral information, i.e., obtaining the resolution of the spectral information and thereby be able to extract spectral lines—thus determining a spectral line position—from such spectral information, hence avoiding all the uncertainty associated with pixel based methods. It is also an object of the present invention a computational apparatus configured to implement such method.

Abstract: A spectrometer system and method including a laser source for directing a laser beam to a sample producing plasma radiation on the sample. At least one fiber of a fiber bundle is connected to an illumination source for directing light to the sample. A spectrometer subsystem receives plasma radiation from the sample via the detection fiber bundle. A camera receives light from the illumination source reflected off the sample for detecting the presence of the sample.

Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system includes: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further includes a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

Abstract: An apparatus and method are disclosed for monitoring and/or detecting concentrations of a chemical precursor in a reaction chamber. The apparatus and method have an advantage of operating in a high temperature environment. An optical emissions spectrometer (OES) is coupled to a gas source, such as a solid source vessel, in order to monitor or detect an output of the chemical precursor to the reaction chamber. Alternatively, a small sample of precursor can be periodically monitored flowing into the OES and into a vacuum pump, thus bypassing the reaction chamber.

Abstract: Methods for matching semiconductor processing chambers using a calibrated spectrometer are disclosed. In one embodiment, plasma attributes are measured for a process in a reference chamber and a process in an aged chamber. Using a calibrated light source, an optical path equivalent to an optical path in a reference chamber and an optical path in an aged chamber can be compared by determining a correction factor. The correction factor is applied to adjust a measured intensity of plasma radiation through the optical path in the aged chamber. Comparing a measured intensity of plasma radiation in the reference chamber and the adjusted measured intensity in the aged chamber provide an indication of changed chamber conditions. A magnitude of change between the two intensities can be used to adjust the process parameters to yield a processed substrate from the aged chamber which matches that of the reference chamber.

Abstract: In accordance with an example embodiment of the invention, a detector assembly for an analyzer device for analysis of elemental composition of a sample using optical emission spectroscopy is provided. The detector assembly comprises an exciter for generating an excitation focused at a target position to invoke an optical emission from a surface of the sample at the target position; and a light collection arrangement for transferring the optical emission to a spectrometer. The light collection arrangement comprises a concave spherical mirror, an optical receiver arranged in an image point in the principal axis of the concave spherical mirror and a folding mirror including at least one aperture. The exciter is arranged with respect to the light collection arrangement such that the excitation is transferred towards the target position through said at least one aperture, and the folding mirror is arranged between the concave spherical mirror and the optical receiver such that the folding mirror folds the principal axis of the concave spherical mirror towards the target position and such that said at least one aperture is aligned with the principal axis of the concave spherical mirror to allow transferring optical emission reflected from the concave spherical mirror therethrough towards the optical receiver.
