With the advancement of technology, the LED industry has seen significant growth, and one particular wavelength that has gained attention is the 850nm LED. This article delves into the world of 850nm LEDs, exploring their applications, advantages, challenges, and the future of this technology.

Introduction to 850nm LEDs

850nm LEDs, also known as infrared LEDs, emit light at a wavelength of 850 nanometers. This makes them fall within the near-infrared spectrum, which is just beyond the visible light range. The use of 850nm LEDs has been on the rise due to their unique properties and wide range of applications.

Applications of 850nm LEDs

One of the primary applications of 850nm LEDs is in optical communication systems. These LEDs are used in fiber optic networks for transmitting data over long distances. Their ability to penetrate dust and water makes them ideal for underwater communication and other harsh environments.

Additionally, 850nm LEDs are widely used in medical imaging devices. They provide a clear and detailed image of the human body, making them essential for various diagnostic procedures. The near-infrared light emitted by these LEDs can penetrate tissues and provide a non-invasive way to visualize internal organs and blood vessels.

Another significant application of 850nm LEDs is in automotive lighting. They are used in rear lights, brake lights, and turn signals due to their high brightness and energy efficiency. Moreover, 850nm LEDs are also used in barcode scanners, laser pointers, and remote controls.
