Optical sensor with an optical element transmissive to warming radiation
First Claim
Patent Images
1. An optical sensor, comprising:
- a housing;
a radiation emitter disposed within the housing; and
an optical element through which the radiation is emitted, wherein the optical element comprises;
a base substrate including a material that is substantially transparent to a warming radiation; and
a warming coating that absorbs warming radiation operatively coupled to the base substrate such that heat absorbed by the warming coating is transferred to the base substrate thereby heating the base substrate.

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.
