Introduction to Infrared LED 950nm

Infrared LED 950nm, also known as 950nm infrared LED, is a type of light-emitting diode that emits infrared radiation at a wavelength of 950 nanometers. These LEDs are widely used due to their high efficiency, long lifespan, and compact size. The 950nm wavelength falls within the near-infrared spectrum, which is invisible to the human eye but can be detected by various sensors and devices.

Technology of Infrared LED 950nm

The technology behind 950nm infrared LEDs involves the use of semiconductor materials, primarily gallium arsenide (GaAs), gallium indium phosphide (GaInP), and aluminum gallium indium phosphide (AlGaInP). These materials are chosen for their ability to emit infrared radiation at the desired wavelength. The manufacturing process includes epitaxial growth, wafer fabrication, and packaging, which are crucial for ensuring the performance and reliability of the LEDs.

Epitaxial growth is a technique used to create a thin layer of semiconductor material on a substrate. This layer, known as the epitaxial layer, is carefully designed to have the desired composition and crystal structure for infrared emission. Wafer fabrication involves slicing the epitaxial layer into individual chips, which are then processed to improve their electrical and optical properties. Finally, the chips are packaged into modules, which can be integrated into various devices.
