    Abstract: Increasing the precision of process monitoring may be improved if the sensors take the form of travelling probes riding along with the flowing materials in the manufacturing process rather than sample only when the process moves passed the sensors fixed location. The probe includes an outer housing hermetically sealed from the flowing materials, and a light source for transmitting light through a window in the housing onto the flowing materials. A spatially variable optical filter (SVF) captures light returning from the flowing materials, and separates the captured light into a spectrum of constituent wavelength signals for transmission to a detector array, which provides a power reading for each constituent wavelength signal.

    Abstract: An optical assembly includes a housing, and an optical filter and an optical compensator disposed within the housing. The optical filter is oriented at a first non-zero angle in a first tilt direction with respect to an optical axis of the optical assembly. The optical compensator is oriented at a second non-zero angle in a second tilt direction with respect to the normal of the optical axis of the optical assembly. The optical filter is configured to pass, to the optical compensator, a portion of an optical beam that impinges on the optical filter along an optical axis of the optical assembly, such that the portion of the optical beam is offset from the optical axis. The optical compensator is configured to cause the portion of the optical beam to propagate out of the optical assembly along the optical axis of the optical assembly (or with a minimized offset).

    Abstract: A spectroscopic assembly (165) may include a spectrometer (110). The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe (120) to transfer the light reflected from the sample. The light pipe may include a first opening (146) to receive the spectrometer. The light pipe may include a second opening (148) to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.
