With the rapid development of technology, infrared LEDs with a wavelength of 850nm have become increasingly popular in various applications. This article aims to provide an in-depth introduction to the industry of infrared LEDs 850nm, covering their characteristics, applications, and future prospects.

Introduction to Infrared LEDs 850nm

Infrared LEDs, also known as IR LEDs, are semiconductor devices that emit infrared light. The 850nm wavelength falls within the near-infrared spectrum, which is invisible to the human eye. These LEDs are widely used in various applications due to their high efficiency, low cost, and long lifespan. The 850nm infrared LED emits light with a longer wavelength than other infrared LEDs, such as 940nm or 1,060nm. This longer wavelength allows for a greater penetration depth in materials, making it suitable for applications requiring deep detection or sensing. Additionally, 850nm infrared LEDs have a lower cost and higher brightness compared to other infrared LEDs, making them an ideal choice for many applications.
