Attend this free of charge online event presented by InfraTec for an introduction to the different wavelength ranges in which infrared thermography enables precise temperature measurement of objects made from a wide variety of materials. Take a closer look at short-wave infrared (SWIR), mid-wave infrared (MWIR) and long-wave infrared (LWIR). Participants will also learn about the additional possibilities offered by spectral thermography and the requirements this places on infrared cameras and software.

Spectral IR thermography uses adapted wavelength windows and therefore enables precise temperature measurements considering the specific IR properties of the object and the measurement situation. Selecting suitable spectral filters, for example, allows temperature measurement of objects behind a glass pane, or even specifically of the glass surface itself.
Fields for spectral thermography
Spectral filters select radiation in defined infrared ranges to consider the specific IR properties of the respective measurement situation. This allows any interfering background radiation to be suppressed and measurement errors to be avoided.
However, not all IR-protective windows offer, for instance, complete IR transmission and thus have unwanted radiometric influence. This can be masked by adapted spectral filters to ensure a correct radiometric measurement of an object behind the window. Likewise, interfering radiation from flames can be suppressed in order to measure “through the flame.” In contrast, gases in a flame can be identified with the help of spectral filters.
