Abstract: An optical apparatus for measurement of industrial chemical processes. The analyzer uses Raman scattering and performs measurement of chemical concentrations in continuous or batch processes. The analyzer operates at a standoff distance from the analyte (or analytes) and can measure concentrations through an optical port, facilitating continuous, non-destructive, and non-invasive analysis without extracting the analyte or analytes from the process. The analyzer can measure one or several solid, liquid, or gaseous analytes, or a mixture thereof.

Abstract: Apparatus is disclosed for providing auxiliary cooling and thermal stability to a temperature sensitive opto-electronic component. The disclosed apparatus comprising a primary thermal control system having a first thermal connection with a primary structure supporting at least one component of an optical system and a second thermal connection being thermally connected with an external environment; and an auxiliary thermal control system having a first thermal connection being thermally connected with the temperature sensitive opto-electronic component, and the auxiliary thermal control system having a second thermal connection being thermally connected with the primary thermal control system whereby the auxiliary thermal control system provides cooling to the temperature sensitive opto-electronic component and the primary thermal control system provides additional cooling to the auxiliary thermal control system through temperature regulation of the primary structure.

Abstract: A method for reducing reflection of undesirable light in an opto-electronic package includes the coating of the interior surfaces of the package with light absorbing materials. Accordingly, when stray or scattered light is incident on package surfaces, reflections are minimized and therefore the optical noise, interference and feedback are reduced.
