Today, near infrared LED technology has become an integral part of numerous industries, offering a wide range of applications.

Technology of Near Infrared LED

Near infrared LED technology is based on the principle of electroluminescence, where a semiconductor material emits light when an electric current is applied. Near infrared LEDs are designed to emit light in the near infrared spectrum, which is the range of light wavelengths between visible light and microwaves. The typical wavelength range for near infrared LEDs is from 700 to 1500 nanometers.

The main materials used in near infrared LED manufacturing include gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium nitride (InGaN). These materials have excellent optical and electrical properties, making them ideal for near infrared LED production. The manufacturing process involves epitaxial growth, where layers of semiconductor materials are deposited on a substrate to create a p-n junction. This junction then emits light when an electric current is applied.
