This article delves into the world of 950nm LEDs, exploring their unique properties, applications, and the potential impact they could have on various industries.

Introduction to LED 950nm

LEDs, or light-emitting diodes, are semiconductor devices that emit light when an electric current passes through them. The color of the light emitted by an LED is determined by the energy bandgap of the semiconductor material used in its construction. LEDs can be engineered to emit light across a wide range of wavelengths, from ultraviolet to infrared. The 950nm LED, specifically, falls within the near-infrared region of the electromagnetic spectrum.
