Abstract: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

Abstract: Embodiments of the systems can be configured to receive electromagnetic emissions of a substrate (e.g., a build material of a part being made via additive manufacturing) by a detector (e.g., a multi-spectral sensor) and generate a ratio of the electromagnetic emissions to perform spectral analysis with a reduced dependence on location and orientation of a surface of the substrate relative to the multi-spectral sensor. The additive manufacturing process can involve use of a laser to generate a laser beam for fusion of the build material into the part. The system can be configured to set the multi-spectral sensor off-axis with respect to the laser (e.g., an optical path of the multi-spectral sensor is at an angle that is different than the angle of incidence of the laser beam). This can allow the multi-spectral sensor to collect spectral data simultaneously as the laser is used to build the part.

Abstract: Provided are a device (4) and a method for online measuring a spectrum for a laser device. The device (4) for online measuring a spectrum for a laser device includes: a first optical path assembly (G1) and a second optical path assembly (G2), and the second optical path assembly (G2) and the first optical path assembly (G1) constitute a measurement optical path. The second optical path assembly (G2) includes: an FP etalon (15) and a grating (18). The homogenized laser beam passes through the FP etalon (15) to generate an interference fringe. The grating (18) is arranged after the FP etalon (15), or is arranged before the FP etalon (15) in the measurement optical path, and is configured to disperse the laser beam passing through the FP etalon (15). A high precision measurement in a wide range for a central wavelength of a laser beam and an accurate measurement for spectral parameters of a corresponding FWHM and E95 are achieved through an arrangement of the FP etalon and the grating “in series” in the measurement optical path. There is no moving element in the measurement optical path, the structure is simple and compact, the measurement precision is high, and the stability is high. The corresponding measurement algorithm is simple and efficient, and has an extremely high scientific research or commercial application value.

Abstract: Systems, apparatuses and methods for rapidly evaluating light transmission through coatings including paints, primers, thin films, surfacing films, laminates and the like are disclosed. The system includes a light source for transmitting light through a coating sample. A sample holder holds the coating sample in a position to receive the incident light. A spectrometer measures an amount of the transmitted light that passes through the coating sample. Optionally, one or more optical filters may be used to condition any transmitted light that passes through the coating sample to reduce the intensity of the light outside of wavelengths of interest. An opaque cover encloses the spectrometer, the one or more optional optical filters, and at least part of the sample holder to prevent light other than the transmitted light from the light source from entering the spectrometer such that any transmitted light passing through the coating sample can be accurately evaluated.
