Introduction to 850nm LED Light

850nm LED light is a type of LED that emits light at a wavelength of 850 nanometers, which falls within the near-infrared spectrum. Unlike visible light, near-infrared light is not visible to the human eye. However, it has numerous applications in various industries, including medical, industrial, and consumer electronics.

Technology of 850nm LED Light

The technology behind 850nm LED light involves the use of gallium arsenide (GaAs) or gallium nitride (GaN) as the semiconductor material. These materials have excellent electrical and optical properties, making them ideal for LED production. The manufacturing process involves epitaxial growth, which involves depositing a thin layer of semiconductor material on a substrate to create a p-n junction.

During the epitaxial growth process, the composition and thickness of the semiconductor layers are carefully controlled to achieve the desired emission wavelength. After the epitaxial growth, the LED chips are then diced, packaged, and tested to ensure their performance and reliability.
