ABSTRACT:
An optical gas sensor includes an optical element that is substantially transparent to both monitoring radiation and warming radiation. Such an optical element facilitates the removal of warming radiation from the optical gas sensor, thereby preventing an increase in the internal temperature of the sensor during use. Additionally, the warming radiation that is emitted from the optical gas sensor may be used to warm one or more windows of a sampling component that is configured for use with the sensor.
