    Abstract: A diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The grating or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained.

    Abstract: A sensor having a several groups of detectors for gas, agent or interferent detection. The detectors may have various fields of view. The detectors may be placed in particular locations of an array and connected in a certain way as groups such that the resultant groups have essentially the same fields of view. The detectors of a group may be sensitive to the same wavelength of radiation. The array of detectors may be placed in a vacuum sealed package having a substrate and a topcap. The topcap may have bandpass filters on the inside surface over the respective filters for selecting the wavelength of radiation that each detector may detect.

    Abstract: A self-cleaning optical probe includes a probe body having a window with a surface oriented toward a sample under investigation. A sampling beam carrying wavelengths representative of the sample passes into the probe body through the window for analysis. A conduit, preferably forming part of the probe body, is used to carry a fluid to the surface of the window oriented toward the sample, and a partition proximate to the window is used to direct the fluid across the window as a laminar flow. The partition further includes an aperture through which the sampling wavelengths pass. This partition also permits a portion of the fluid to pass though the aperture to ensure that the sample under investigation does not reach the window. The fluid may be a liquid or gas, and is preferably a solvent to maximize window cleaning. Although the fluid may be discharged without entering into the environment being sampled, the fluid may also be discharged into the sample, depending upon the application, volume of the respective fluid/sample flows, and other such factors.
