Abstract: A spectral sensor includes a wiring substrate which has a principal surface; a light detector which is disposed on the principal surface of the wiring substrate and is electrically connected to the wiring substrate; spacer which is disposed around the light detector, on the principal surface of the wiring substrate; and a Fabry-Perot interference filter which has a light transmission region and is disposed on the principal surface of the wiring substrate with the spacer therebetween. The spacer support the Fabry-Perot interference filter in a surrounding region of the light transmission region and the spacer is arranged to form opening communicating with an inner side of the surrounding region and an outer side of the surrounding region, when viewed from a light transmission direction in the transmission region.

Abstract: A spatial Fourier transform spectrometer is disclosed. The Fourier transform spectrometer includes a Fabry-Perot interferometer with first and second optical surfaces. The gap between the first and second optical surfaces spatially varies in a direction that is orthogonal to the optical axis of the Fourier transform spectrometer. The Fabry-Perot interferometer creates an interference pattern from input light. An image of the interference pattern is captured by a detector, which is communicatively coupled to a processor. The processor is configured to process the interference pattern image to determine information about the spectral content of the input light.

Abstract: A spectrometer is provided which comprises a Virtually Imaged Phased Array member configured to receive an electromagnetic input radiation and to generate an electromagnetic output radiation, in which a spectrum of the electromagnetic output radiation is dispersed along a dispersion axis (x) transverse to an optical axis (z) of propagation of the electromagnetic output radiation; a Fourier lens adapted to convert the output electromagnetic radiation into a spectral pattern; an image sensor adapted to detect the spectral pattern; and at least one diffraction mask arranged along the optical axis (z) for propagating the output electromagnetic radiation, in a position not coincident with a spectral plane of the spectrometer. Through the diffraction mask, which comprises a material blocking the transmission of the output electromagnetic radiation, an aperture is obtained which allows the transmission of the output electromagnetic radiation, and whose edge comprises at least one inclined segment.

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 wavelength or narrow range of wavelengths to pass through.

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.
