Abstract
System and apparatus for robust, portable gas detection. Specifically, this disclosure describes apparatuses and systems for optical gas detection in a compact package using two optical pathways. There is a need for a very compact, low-power, gas detection system for gases such as CO2, NOx, water vapor, methane, etc. This disclosure provides an ultra-compact and highly stable and efficient optical measurement system based on principals of optical absorption spectroscopy using substantially collinear pathways.
