Abstract: Methods, apparatuses, and systems for diagnosing misalignment in gas detecting devices are provided. An example method may include causing at least one detector component of a receiver element of the open path gas detecting device to generate a first light intensity indication corresponding to first infrared light; causing the at least one detector component to generate a second light intensity indication corresponding to second infrared light; and generating an alignment indication based at least in part on the first light intensity indication and the second light intensity indication.

Abstract: Methods, apparatuses, and systems for improving gas detecting devices are provided. An example gas detecting device may include a receiver element. In some examples, the receiver element may include a sample filter component and a reference filter component. In some examples, the sample filter component may be positioned coaxially with the reference filter component.

Abstract: Embodiments relate generally to systems and methods for filtering unwanted wavelengths from an IR detector. In some embodiments, it may be desired to remove or reduce the wavelengths absorbed by water, to reduce the effects of water on the detection of the target gas. In some embodiments, a filter glass may be used in the IR detector, wherein the filter glass comprises one or more materials that contain hydroxyls in their molecular structure, and wherein the spectral absorption properties of the filter glass are operable to at least reduce wavelengths of light absorbed by water from the optical, thereby reducing the IR detector's cross sensitivity to water.
