In this article, we will delve into the world of LED IR 850nm, exploring its technology, uses, benefits, and future prospects.

Introduction to LED IR 850nm Technology

LED IR 850nm technology involves the use of LEDs that emit light at a wavelength of 850 nanometers. This falls within the near-infrared region of the electromagnetic spectrum, which is not visible to the human eye. The key components of an LED IR 850nm device include the LED itself, a lens or lens array for focusing the light, and a sensor or camera capable of detecting the emitted infrared light.

How LED IR 850nm Works

The working principle of LED IR 850nm technology is quite straightforward. When an electric current is applied to the LED, it emits photons at a specific wavelength, in this case, 850nm. These photons are then focused by the lens or lens array onto a target surface. The target surface reflects the infrared light back to the sensor or camera, which captures the image or data for further processing.
