Introducing the 850nm IR LED: A Game-Changer in the World of Infrared Technology

Introduction to IR LEDs

Infrared (IR) light is a form of electromagnetic radiation that has wavelengths longer than those of visible light but shorter than those of microwaves. It is widely used in various applications, including remote controls, security systems, medical devices, and scientific research. At the heart of many of these applications are infrared light-emitting diodes (LEDs), which are semiconductor devices that emit light when an electric current passes through them. Among the different types of IR LEDs, the 850nm IR LED stands out for its unique properties and wide range of applications.

What is an 850nm IR LED?

An 850nm IR LED is a type of IR LED that emits light at a wavelength of 850 nanometers (nm). This falls within the near-infrared spectrum, which is just beyond the range of human vision. The 850nm wavelength is particularly useful because it allows for efficient transmission through various materials, including plastics, glass, and water, making it ideal for a variety of applications.
