1. An infrared (IR) temperature monitoring system, comprising:
- a protective housing having an open end and closed end, wherein the protective housing is plastic;
an IR temperature sensor element (sensor element) having a protective sensor housing which encases an IR element,wherein the protective housing encases the sensor element and the sensor housing,wherein the protective housing is a cap that shields the sensor element from one or more environmental effects; and
a metallic frame positioned upon an inner portion of the closed end of the protective housing, the metallic frame encompasses a transmissive window in the closed end of the protective housing, and the metallic frame provides a stable temperature around the transmissive window,wherein the metallic frame is a conductive top hat,wherein the conductive top hat establishes a stable thermal link between the transmissive window and the sensor element.

Abstract
Infrared (IR) temperature measurement and stabilization systems, and methods related thereto are provided. One or more embodiments passively stabilizes temperatures of objects in proximity and within the path between an infrared (IR) sensor and target object. A protective housing may encase an IR sensor, which may include a sensing element or IR element, a circuit or signal processor, and a housing seal plug. The IR element may be thermally bonded with a frame or conductive top hat.
