This characteristic makes it ideal for covert and long-distance operations.

Technology of High Power IR LED 940nm

The technology behind high power IR LED 940nm involves the use of semiconductor materials, primarily gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), to create a diode that emits infrared light. The diode is encapsulated in a housing that protects it from external elements and helps in focusing the emitted light. The process of manufacturing high power IR LED 940nm involves several steps, including material growth, device fabrication, and packaging. Material growth typically involves epitaxial deposition, where a thin layer of semiconductor material is deposited on a substrate to create a p-n junction. Device fabrication includes the creation of the p-n junction, which is essential for the emission of light. Finally, the LED is packaged with a lens or reflector to enhance its light output and directivity.
