What Does FIR Stand For?

FIR stands for Far InfraRed

FIR, or Far InfraRed, refers to a specific range of infrared radiation with wavelengths typically between 15 micrometers and 1 millimeter. This part of the electromagnetic spectrum is primarily associated with thermal radiation emitted by objects at relatively low temperatures. FIR is widely used in various applications, including thermal imaging, medical therapy, and environmental monitoring, due to its ability to penetrate materials and its relatively low energy, making it safe for diverse uses.
