Abstract: Provided a terahertz-wave detection element with high spatial resolution and suppressing a crack occurrence. A method of manufacturing the detection element capable of detecting a spatial intensity distribution of a terahertz wave includes: a step of forming an oxide layer on one main surface of a first substrate consisting of an electro-optic crystal; a step of joining the one main surface of the first substrate and a second substrate by an adhesive consisting; a step of thinning the first substrate of a joined body, to a thickness of 1-30 μm by polishing the first substrate; and a step of obtaining a large number of terahertz-wave detection elements by cutting the joined body. The oxide layer is formed such that the first substrate becomes convex to a side of the one main surface by causing a tensile stress to act on it.

Abstract: A spark-induced breakdown spectroscopy apparatus can have a housing with an inlet and an outlet that define an analyte flow path. A laser can define a laser pathway generally transverse to an intersecting the analyte flow path. A pair of electrodes, which can have insulating shields, can be mounted within the housing and can define a spark path. An optical detection element defines an optical path. The apparatus can be used to identify an aerosolized analyte.

Abstract: The invention relates to controllable Fabry-Perot interferometers which are produced with micromechanical (MEMS) technology. Micromechanical interferometers of the prior art have a disadvantage of significantly attenuating infrared radiation. In the inventive solution there is a gap in at least one mirror, serving as a layer of the mirror. The other layers of the mirrors can be made of polycrystalline silicon, which has a negligible attenuation at the infrared range. It is also preferable to provide a hole or a recess in a substrate at the optical area of the interferometer.

Abstract: Optical radiation from a sample is received by the slit and it is passed through an aperture in a reflective plane of a folding mirror towards a curved reflective surface of a collimating mirror. The slit and the curved reflective surface have a common optical axis. The reflective plane and the curved reflective surface face each other. The optical radiation passed through the folding mirror is collimated by the curved reflective surface. The collimated optical radiation is directed to the reflective plane of the folding mirror by the curved reflective surface. The collimated optical radiation is reflected in a direction other than the common optical axis of the slit and the curved reflective surface by the reflective plane.

Abstract: An apparatus for performing Raman spectral analysis of a sample is described, comprising a coherent light source, an first optical chain to direct the coherent light to impinge on the sample, a second optical chain to direct the scattered light onto a diffraction grating, and a third optical chain to direct the diffracted light onto detection array. The diffraction grating is a stairstep with a metalized surface, and a plurality of metalized stripes on a flat surface is disposed in a direction orthogonal to the long dimension of the stairsteps. The region between the flat surface and the stairstep is transparent. The zeroth-order fringe is selected by a slit and directed onto camera. The resultant interferogram is Fourier transformed to produce a representation of the Raman spectrum.

Abstract: The present invention is directed to a method of utilizing a digital micromirror device (DMD) to spectrally matching a standard or device-independent color. DMD can be fitted on an integrated chip and can provide more than one thousand (1,000) color primary channels for low metameric color matching producing a spectrally matched batch color. This represents a two orders of magnitude improvement in color matching.
