Infrared emitter tube, also known as infrared LED (Light Emitting Diode), is an electronic component that emits infrared light. With the rapid development of technology, infrared emitter tubes have become an indispensable part of various fields such as consumer electronics, automotive, medical equipment, and industrial automation. This article will introduce the development history, classification, application fields, and market prospects of infrared emitter tubes.

Development History of Infrared Emitter Tube

The history of infrared emitter tubes can be traced back to the early 20th century. In 1908, a British scientist named William Henry Culverwell discovered that when a semiconductor is forward biased, it emits infrared radiation. This discovery laid the foundation for the development of infrared emitter tubes. In the 1930s, the United States began to research and develop infrared emitter tubes, and later introduced them to the market. In the 1950s, with the continuous optimization of technology, the performance of infrared emitter tubes was significantly improved, and their application fields were gradually expanded.

Classification of Infrared Emitter Tube

According to the wavelength, infrared emitter tubes can be divided into short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) emitter tubes. According to the working principle, they can be divided into photoelectric infrared emitter tubes and thermal infrared emitter tubes. According to the structure, they can be divided into through-type, surface-type, and integrated type. The choice of infrared emitter tube depends on the specific application requirements.
