    Abstract: A macroscopic fluorescence illumination assembly is provided for use with an imaging apparatus with a light-tight imaging compartment. The imaging apparatus includes an interior wall defining a view port extending into the imaging compartment to enable viewing of a specimen contained therein. The illumination assembly includes a specimen support surface sized and dimensioned for receipt in the imaging compartment, and oriented to face toward the view port of the imaging apparatus. The support surface is substantially opaque and defines a window portion that enables the passage of light there through. The window portion is selectively sized and dimensioned such that the specimen, when supported atop the support surface, can be positioned and seated over the window portion in a manner forming a light-tight seal substantially there between. The illumination assembly further includes an excitation light source, and a bundle of fiber optic strands having proximal ends thereof in optical communication with the light source. The distal ends of the strands terminate proximate the window portion of the support surface. The distal ends each emit a respective beam of light originating from the light source which are then collectively directed toward the window portion and into a bottom side of the specimen wherein the diffused light passes there through and exits a topside thereof for receipt through the view port to view the fluorescence of the specimen.

    Abstract: A method and apparatus is provided for determining a property of an analyte using a sensing layer whose optical response changes with the analyte. The apparatus includes a housing with an optically transparent window for receiving the sensing layer. The window passes optical stimulation to the sensing layer and the optical response from the sensing layer. A stimulating light emitter is coupled to a first face of an optical body monolithically coupled to the window and a light detector is coupled to a second face of the optical body for receiving the response. The optical response changes as the concentration of the analyte changes. Reference molecules included in the sensing layer can provide a calibration signal to a second light detector mounted on a third face of the optical body. The first, second and third faces of the optical body are different and not coplanar.

    Abstract: A system and method for leak testing a plurality of hermetic electronic devices of the type that have an internai chamber that is isolated from ambient conditions by a seal structure is advantageously designed to be able to calculate the leak rate of each individual device in a marner that is independent of structural manufacturing variances that typically exist within a sampling of such devices. The method preferably involves positioning a plurality of the hermetic electronic devices within a test area, and then stimulating the hermetic electronic devices with a modulated input of energy, such as by varying the ambient pressure about the devices. A property such as the physical position of one portion of a lid of each of the hermetic electronic devices is then sensed. The sensed property is one that is known to change as a first function of the modulated input of energy and also as a second function of pressure conditions within the hermetically sealed internal chamber. The first and second functions are linearly independent of each other. By comparing the stimulation of the devices to the sensed property and by discriminating using the two known functions a leak rate is determined for each individual device that is substantially independent of variances, such as differences in lid thickness that may exist between the different devices. Accordingly, an accurate determination of leak rate may be made with a minimum of calibration.

    Abstract: A non-dispersive infrared (NDIR) multi-gas analyzer (405) has an optical element (950) that is positioned with respect to the axis of incident IR radiation such that it passes nearly all of the IR energy within a narrow band pass to one detector (540) and reflects nearly all of the IR energy outside the narrow band pass to another detector (535). Thus, the optical element (950) simultaneously functions both as a narrow band pass filter and a beam splitter, which transmits nearly all the IR radiation within a band pass and reflects nearly all the IR radiation outside the band pass. Additionally, the separation of the incoming energy can be achieved without an extended roll off. This allows using a reference transmission band that is very close to the absorption band of the gases of interest. It more specifically allows using a reference transmission band that is located between the absorption bands for hydrocarbons and carbon dioxide in an infrared analyzer that uses beam splitters.
