摘要： A gas measurement system of this invention includes a detector assembly having a beamsplitter adapted to separate infrared radiation into a first beam and a second beam and a mirror adapted to receive the first beam from the beamsplitter. The first and second beams are directed to first and second detectors that are disposed in a common plane. In one embodiment, the optical elements are provided on or in an optical block. In another embodiment, the gas measurement system includes a housing that contains an infrared absorption gas measurement assembly, a luminescence quenching gas measurement assembly, and a processor that is programmed to measure gas constituents of a gas flow based on an output of the infrared absorption gas measurement assembly and the luminescence quenching gas measurement assembly.

摘要： A heater for a window of an optical gas sensor is provided. The heater may be positioned over a portion of the window or may form at least a portion of the window. Alternatively, the heater may be separate from the optical gas sensor and positionable over the window either in contact therewith or in close proximity thereto. In one embodiment, the heater is substantially transparent to the relevant wavelengths of electromagnetic radiation that are used in optical monitoring of respiratory gases, anesthetic agents, or the like. Alternatively, the heater may be configured so as to provide a substantially unobstructed optical pathway through the window. Optical gas sensors and complementary transducers that include the heater are also disclosed.
