Abstract
In implementations, an open path gas detector is disclosed that can include imaging or non-imaging optical components. The detector can include components that allow for misalignment of radiation received by the detector of about 1 without causing false alarms. In implementations, the detector can include a beam splitter or a wavelength-division multiplexing filter to allow for more of the radiation received by the detector to be detected by the sensors.
