950nm IR LED, or Infrared Light Emitting Diode, has emerged as a crucial component in the field of infrared technology. This type of LED emits infrared light at a wavelength of 950nm, making it suitable for a wide range of applications, including remote controls, surveillance systems, and medical devices. In this article, we will delve into the details of 950nm IR LED technology, its applications, and the future prospects of this innovative technology.

Introduction to 950nm IR LED Technology

950nm IR LED technology is based on the principle of semiconductor physics. When a forward voltage is applied to a semiconductor material, electrons and holes are generated, and when they recombine, infrared light is emitted. The 950nm wavelength falls within the near-infrared spectrum, which is invisible to the human eye but can be detected by various sensors and devices.

Compared to other types of IR LEDs, such as 850nm and 940nm, 950nm IR LEDs offer several advantages. Firstly, they have a longer wavelength, which allows for a greater detection distance and a wider field of view. Secondly, they have a lower cost and are more energy-efficient. Lastly, they have a longer lifespan and are more durable.
