What are SWIR, MWIR, and LWIR – And what do they mean?

Overview Infrared Thermography operates through the infrared region beyond the visible light spectrum. Everything within the infrared wavelength radiates energy that can be visually captured through a thermal imaging device. Each wavelength in the infrared spectrum emits a certain amount of radiation that can be transmitted and captured through a thermal imager operating in that wave band. In infrared thermography, …
