Introduction to Infrared LEDs 850

What are Infrared LEDs 850?

Infrared LEDs, or Light Emitting Diodes, are electronic devices that emit infrared light. The "850" in infrared LEDs 850 refers to the wavelength of the light they emit, which is 850 nanometers. These LEDs are widely used in various applications due to their unique properties and advantages. In this article, we will explore the world of infrared LEDs 850, their applications, and the benefits they offer.

How Do Infrared LEDs 850 Work?

Infrared LEDs 850 work on the principle of electroluminescence. When an electric current passes through a semiconductor material, it releases photons, which are particles of light. In the case of infrared LEDs 850, the semiconductor material used is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which means they can efficiently emit infrared light at a specific wavelength. The structure of an infrared LED 850 consists of a p-n junction, where the p-type and n-type semiconductor materials are joined together. When an electric current is applied, electrons and holes recombine at the junction, releasing infrared photons in the process. The emitted light is then directed through a lens or a collimating optic to enhance its focus and intensity.
