Abstract: Robust and portable gas detection apparatus using at least two optical light sources (220: 320, 330; 420, 430) of different central wavelengths arranged to propagate in the gas detector along a common pathway (280) towards a common detector (240) and adapted to detect the presence and concentration of gases such as C02, NOx, water vapor, methane, etc.

Abstract: A method, a system, and a non-transitory computer readable medium for accurate Raman spectroscopy. The method may include executing at least one iteration of the steps of: (i) performing, by an optical measurement system, a calibration process that comprises (a) finding a misalignment between a region of interest defined by a spatial filter, and an impinging beam of radiation that is emitted from an illuminated area of a sample, the impinging beam impinges on the spatial filter; and (b) determining a compensating path of propagation of the impinging beam that compensates the misalignment; and (ii) performing a measurement process, while the optical measurement system is configured to provide the compensating path of propagation of the impinging beam, to provide one or more Raman spectra.

Abstract: An embodiment of a system is described that comprises a light source configured to produce a light beam; a collimating lens disposed on a movable mount, wherein the collimating lens is configured to capture the light beam and produce a substantially collimated beam; and an aspheric diffuse ring optic configured to receive the collimated beam and produce a spot on a surface that comprises a non-uniform radial intensity distribution.
