What is an Infrared Inspection Window?

A window is used to separate environments of differing pressures or temperatures, while allowing energy at a specified electromagnetic wavelength to pass between the two environments.  An infrared window (also referred to as a viewport, viewing pane, sightglass, port or grill) is a generic term used to describe an inspection point that is designed to allow infrared radiation to transmit to the outside environment. Simply put, an infrared (IR) window is a data collection point for a thermal camera. All IR windows must fulfill the strength, rigidity and environmental requirements of the type of equipment into which it is installed. It must also be compatible with the infrared equipment being used.

Some IR windows are simply a housing with an open center, and a cover that secures the opening.  Typically, the IR window housing will contain a grill or an optic. The design, size, and material used are driven by considerations such as the required field‐of‐view, camera lens compatibility, intended environment, sealing requirements, and safety considerations.
