Far IR LED, or far infrared light-emitting diode, is a specialized type of semiconductor device that emits light in the far infrared region of the electromagnetic spectrum. This region spans wavelengths from about 700 nanometers to 1 millimeter, making it invisible to the human eye. Far IR LEDs are widely used in various applications due to their unique properties and benefits. This article will provide an in-depth introduction to the far IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Far IR LED Technology

The development of far IR LED technology dates back to the late 20th century. Initially, the focus was on the research and development of infrared LEDs for military and aerospace applications.
