Glass production processes cover a wide range of temperatures, from room temperature to over 1600°C. Non-contact thermal imaging is well suited to gather temperature information about these processes, especially where contact temperature methods will disturb the process or will not survive the harsh environment. For a given process, the type of information gathered depends strongly on the infrared wavelengths used in the detector. With hot glass, shorter IR wavelengths (NIR and SWIR) typically reveal information about the interior temperatures of the glass, while longer wavelengths (MWIR and LWIR) reveal information about the surface temperatures. For molds, plungers, and other glass-forming equipment, shorter wavelengths reveal surface temperatures, while longer wavelengths tell more about reflectivity and wear of the surfaces. Combining information from different parts of the IR spectrum gives us a more complete picture of heat transfer during glass production. This, in turn, allows us to understand and solve more complex production problems.
