One of the primary applications of 850nm infrared LEDs is in the medical field. These LEDs are used in endoscopy, where they provide illumination for internal examinations. Their ability to penetrate biological tissue makes them ideal for minimally invasive procedures. Additionally, 850nm infrared LEDs are used in biometric authentication systems, such as fingerprint scanners and facial recognition devices, due to their high sensitivity and low interference from ambient light.

In the automotive industry, 850nm infrared LEDs are employed in advanced driver-assistance systems (ADAS). These systems use infrared technology to detect objects and pedestrians in low-light conditions, enhancing safety and reducing accidents. Furthermore, 850nm infrared LEDs are used in automotive diagnostics and in-car entertainment systems, providing a reliable and efficient source of infrared light.

Consumer electronics also benefit from the use of 850nm infrared LEDs. They are commonly found in remote controls, where they enable long-range communication with electronic devices. Additionally, 850nm infrared LEDs are used in gaming devices, providing a means for wireless communication between the controller and the console.

Technology and Manufacturing

The manufacturing process of 850nm infrared LEDs involves several steps, including wafer fabrication, epitaxial growth, and device fabrication. The wafer is typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which are suitable materials for infrared LED production. Epitaxial growth is used to create a thin layer of the active material on the wafer, which emits the infrared light. Device fabrication involves the formation of the LED structure, including the p-n junction and the metal contact.

One of the key challenges in the manufacturing of 850nm infrared LEDs is achieving high efficiency and stability. Researchers and engineers are continuously working on improving the material quality, reducing defect density, and optimizing the device design to enhance the performance of these LEDs.
