Far IR LED, short for far-infrared light-emitting diode, is a type of semiconductor device that emits infrared radiation in the far-infrared region of the electromagnetic spectrum. This technology has found extensive applications in various fields, such as thermal imaging, communication, medical diagnostics, and environmental monitoring. In this article, we will delve into the industry of far IR LED, exploring its development, applications, and future prospects.

Introduction to Far IR LED Technology

Far IR LED technology has been in development for many years, with significant advancements in the past few decades. The working principle of far IR LED is based on the direct bandgap of semiconductor materials, which allows electrons to be excited and emit far-infrared radiation when forward biased. Common semiconductor materials used in far IR LED include HgCdTe, InAsSb, and InAs.

Compared with conventional light-emitting diodes (LEDs), far IR LEDs have several unique advantages. Firstly, far IR radiation has a longer wavelength, which makes it less likely to be absorbed by atmospheric gases, enabling long-distance transmission. Secondly, far IR radiation has high thermal radiation efficiency, making it suitable for applications in thermal imaging and temperature measurement. Lastly, far IR LEDs have a wide spectral range, covering the entire far-infrared region from 1 to 1000 μm.
