Introduction to IR LED 880 nm
What is an IR LED 880 nm?
An IR LED 880 nm, also known as an infrared light-emitting diode with a peak emission wavelength of 880 nanometers, is a type of optoelectronic device that emits infrared light. These devices are widely used in various applications, including remote control, communication, and sensing. Unlike visible light, infrared light is not visible to the human eye, making it suitable for applications where stealth or covert operation is required.
Working Principle of IR LED 880 nm
The working principle of an IR LED 880 nm is based on the photoelectric effect. When an electric current is applied to the semiconductor material, electrons are excited and move to the conduction band, releasing energy in the form of photons. The wavelength of the emitted photons depends on the energy gap of the semiconductor material. In the case of an IR LED 880 nm, the energy gap is such that the emitted photons have a wavelength of 880 nm.
