摘要： An adjustable mount for an optical device in a laser spectroscopy system is provided. The adjustable mount includes body configured to mount to a process and a reflector mount having a feature configured to mount an optical device. An interface between the body and the reflector mount allows relative motion between the reflector mount and the body. At least one alignment device is configured to engage the reflector mount and the body to fix a position of the reflector mount relative to the body. An optical device is removably mounted to the reflector mount independent of the alignment device and is sealed to the reflector mount.

摘要： An apparatus and method operable for the continuous monitoring of a gas stream including an optical sensor operable to monitor and/or measure Hg concentrations in a flue gas by calculating the absorbance of the ultraviolet light thereby at a range of wavelength 253.7 nm+/−0.05 nm. The apparatus therefore provides as a spectrally narrow UV light source, a mercury lamp. The spectrally broad UV light source includes a UV LED. A 2×2 coupler is provided to mix the narrow and broad UV light energy which is propagated through the gas stream. The invention recognizes that measurement of radiation absorption at the 254 nm+/−1.5 nm range will result in not only from Hg0, but also from the SO2 component in the flue gas. To compensate for sulphur dioxide, measurement of energy absorption for both specially narrow radiant energy in the 253.7 nm+/−0.5 nm range, as well as ultraviolet (UV) light at a comparatively spectrally broad range of 254 nm+/−20 nm is performed recognizing that sulphur dioxide in the emitted flue gas will tend to absorb the ultraviolet light over the broader UV range. Ultraviolet light absorption over the broader range is calculated to provide a correction factor used to correct energy absorption values over the narrow radiant energy range, providing more accurate measurement of the absorption caused by the presence of mercury.

摘要： An optical sensor system is disclosed including a source module, a detection module, and a heating module. The source module includes a source housing unit having a source window member to emit a detection signal through the source window member. The detection module includes a first detection housing unit having a first detection window member spaced apart from the source module. The detection signal received by the detection module corresponds to an amount of volatile organic compounds (VOC) present in a path of the detection signal between the detection module and the source module. The heating module heats the source window member and the detection window member to remove deposit formation of the VOC there from.
