In this article, we will introduce the 940nm infrared illuminator, its working principle, application fields, advantages, and market prospects.

Introduction to 940nm Infrared Illuminator

The 940nm infrared illuminator is a device that emits infrared light at a wavelength of 940nm. It is widely used in the field of infrared imaging, as it can effectively improve the signal-to-noise ratio of the image and enhance the clarity of the image. The 940nm infrared illuminator is usually composed of an infrared LED light source, an optical lens, and a control circuit.

Working Principle of 940nm Infrared Illuminator

The 940nm infrared illuminator works on the principle of emitting infrared light. When the infrared LED is powered on, it emits infrared light at a wavelength of 940nm. The infrared light then passes through the optical lens, which focuses the light on the target. The target reflects the infrared light, which is then received by the infrared sensor. The received infrared light is converted into an electrical signal, which is then processed by the control circuit to produce the image.
