Endress+Hauser Optical Analysis, Inc. is a manufacturer of optical-based gas sensors for the industrial process, environmental monitoring and clean technology markets. The company's sensors measure the absorption of laser light at specific wavelengths to detect carbon dioxide and water vapor in industrial process control and environmental monitoring applications.
A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
Laser absorption spectrometry (LAS) refers to techniques that use lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS). Optical spectroscopic techniques in general, and laser-based techniques in particular, have a great potential for detection and monitoring of constituents in gas phase .
Spectrometers discriminate the wavelength based on the position the light hits at the detector array allowing the full spectrum to be obtained with a single acquisition. Most spectrometers have a base measurement of counts which is the un-calibrated reading and is thus impacted by the sensitivity of the detector to each wavelength.

George Pickens wore some expensive eye black last week. The Pittsburgh Steelers wide receiver was fined $10,231 by the NFL on Saturday for displaying a "personal message" on his eye black during ...
A single-beam spectrophotometer measures the relative light intensity of the beam before and after a test sample is inserted. Although comparison measurements from double-beam instruments are easier and more stable, single-beam instruments can have a larger dynamic range and are optically simpler and more compact.
Chaz Lanier scored 26 points to lead No. 3 Tennessee to a 96-70 victory over Syracuse in the SEC/ACC Challenge on Tuesday night. The Volunteers (8-0) got a double-double from Igor Milicic with 11 ...
