Abstract: A gas sample chamber (10) for use in a gas analyzer consists of an elongated hollow tube (21) having an inwardly-facing specularly-reflective surface (22) that permits the tube to function also as a light pipe for conducting radiation from a source (20) to a detector (16) through the sample gas. A number of apertures (24) in the wall of the elongated hollow tube permit the sample gas to enter and exit. Particles of smoke and dust of a size greater than 0.1 micron are kept out of the chamber by use of a semi-permeable membrane (28) that spans the apertures in the hollow tube. Condensation of the sample gas components is prevented by heating the sample chamber electrically to a temperature above the dew point of the component of concern.

Abstract: A package for an optical assembly of a type that uses bulk optics in an optical path will require environmental protection from contaminants. It is common to construct a substantially hermetically sealed package to provide environmental protection for the optical assembly but such hermetically sealed packages are expensive to construct and are not completely reliable. Consequently, a package is provided for an optical assembly with the bulk optics encapsulated by a silicone encapsulant and encased within an epoxy layer and supported by a substrate base. The package for the optical assembly thus provides the bulk optics with the required environmental protection from contaminants.

Abstract: A compact low-cost fire detector responds quickly by detecting an increase in the concentration of carbon dioxide gas in the ambient air. The detector also calculates the rate of build-up of carbon dioxide. The detector avoids the use of moving parts by employing a differential temperature black body source of infrared radiation in conjunction with a dual pass band filter. One of the pass bands is located at the 4.26 micron absorption band of carbon dioxide gas and the other pass band is located at 2.20 microns at which none of the atmospheric gases has an absorption band. The latter channel serves as a reference and renders the detector immune to false alarms caused by dust or smoke particles in the air or due to deterioration of certain components. The fire detector makes use of a sample chamber that consists of a serpentine passage in a block of material, the walls of the serpentine passsage being highly reflective so as to act as a light pipe.

Abstract: A non-dispersive infrared (NDIR) multi-gas analyzer has an optical element 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 and reflects nearly all of the IR energy outside the narrow band pass to another detector. Thus, the optical element simultaneously functions both as a narrow band pass filter and a beam splitter, which transmits nearly all the IR energy within a band pass and reflects nearly all the IR energy 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.

Abstract translation: 非分散红外（NDIR）多气体分析仪具有相对于入射IR辐射轴定位的光学元件，使得其将窄带内的几乎所有IR能量传递到一个检测器并几乎全部反射 的窄带外的IR能量通过到另一个检测器。 因此，光学元件同时用作窄带通滤波器和分束器，其在带通内传输几乎所有的IR能量，并将几乎所有的IR能量反射到带通外。 此外，可以实现进入能量的分离而不需要延长的滚降。 这允许使用非常接近感兴趣的气体的吸收带的参考传输带。 更具体地，允许在使用分束器的红外分析器中使用位于碳氢化合物的吸收带和二氧化碳之间的参考传输带。
