Abstract: A system and method include a wavelength shift correction light source emitting wavelength shift correction emission-line light and a spectrometer including: a spectroscopic unit receiving with photoelectric conversion elements rays of dispersed spectral light obtained by dispersing incident light based on wavelength, and outputs electrical signals corresponding to light intensities of the rays of dispersed spectral light; and a unit that measures temperature of the spectroscopic unit. When the wavelength shift correction emission-line light is measured as the incident light with the spectrometer, this system and method determine wavelength shift correction time emission-line wavelength corresponding to wavelength shift correction emission-line light, based on electrical signals from photoelectric conversion elements receiving wavelength shift correction emission-line light, and the measured temperature. The system and method determine wavelength variation from the difference between determined wavelength shift correction time emission-line wavelength and known emission-line wavelength of the wavelength shift correction emission-line light.

Abstract: A system and method for imaging a sample using Raman spectrometry. Optical fibers having opposite first ends and second ends are arranged with the first ends and second ends in respective two-dimensional arrays. The two-dimensional arrays maintain relative positions of the optical fibers to one another from the first ends to the second ends in a way that the first end of each optical fibers of the bundle can simultaneously collect a corresponding Raman signal portion scattered from specific spatial coordinates of the area of the sample. The so-collected Raman signal portions are propagated towards the corresponding second end, from which are outputted and detected simultaneously using an array of detectors.

Abstract: Spectral apparatus includes sensors that output signals indicating the respective energy amounts of a plurality of wavelength components. For each of the sensors, its reference spectral sensitivity is acquired, and an indicator indicating the reference spectral sensitivity of the sensor, is acquired. The deviation of an indicator indicating the spectral sensitivity of the sensor from the indicator indicating the reference spectral sensitivity of the sensor, is expressed by a linear function of an indicator indicating a mechanical error in the spectral apparatus. The indicator indicating the mechanical error in the spectral apparatus, is acquired to adapt a spectral sensitivity set of sensors to a signal set output by the sensors. For each of the sensors, the deviation of the indicator indicating the spectral sensitivity of the sensor from the indicator indicating the reference spectral sensitivity of the sensor, is acquired, so that the spectral sensitivity of the sensor is acquired.

Abstract: The present disclosure describes broadband optical emission sources that include a stack of semiconductor layers, wherein each of the semiconductor layers is operable to emit light of a different respective wavelength; a light source operable to provide optical pumping for stimulated photon emission from the stack; wherein the semiconductor layers are disposed sequentially in the stack such that a first one of the semiconductor layers is closest to the light source and a last one of the semiconductor layers is furthest from the light source, and wherein each particular one of the semiconductor layers is at least partially transparent to the light generated by the other semiconductor layers that are closer to the light source than the particular semiconductor layer. The disclosure also describes various spectrometers that include a broadband optical emission device, and optionally include a tuneable wavelength filter operable to allow a selected pass through.

Abstract: A hand-held synchronous scan spectrometer for in situ analysis of bacteria, viruses, and fungi includes a housing that contains a light source, a first monochromator positioned to receive light from the light source and operable to direct a wavelength of the light from the light source towards a sample, a second monochromator positioned to receive fluoresced light from the sample and light from first monochromator, and a detector disposed within the housing and positioned to receive light output from the second monochromator. The hand-held synchronous scan spectrometer can include a display that is integrated into the housing or can utilize a display of a removable display device (e.g., a cell phone, PDA, tablet, and the like).

Abstract: A spectroscopic assembly may include a spectrometer. The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe to transfer the light reflected from the sample. The light pipe may include a first opening to receive the spectrometer. The light pipe may include a second opening to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.
