Revolutionizing Technology: Unveiling the Power of 940 nm LED Innovations

940 nm LED, or the near-infrared (NIR) LED with a wavelength of 940 nanometers, has emerged as a significant technology in various industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the 940 nm LED industry, covering its technology, applications, market trends, and future prospects.

Technology of 940 nm LED

The 940 nm LED operates in the near-infrared spectrum, which is just beyond the visible light range. This wavelength is particularly attractive for certain applications due to its ability to penetrate certain materials and its minimal interference with human vision. The technology behind the 940 nm LED involves the use of semiconductor materials that emit light at this specific wavelength when an electrical current is applied.

The most common semiconductor materials used in 940 nm LED production are aluminum gallium indium phosphide (AlGaInP) and indium gallium nitride (InGaN). These materials are carefully doped and structured to achieve the desired emission characteristics. The structure typically includes a p-type layer, an active region, and an n-type layer, with the active region being the core of the LED that emits light.
