Revolutionize Night Vision with the IR Illuminator 940nm

As a cutting-edge technology in the field of infrared (IR) illumination, the 940nm IR illuminator has become an indispensable tool in various applications, ranging from scientific research to industrial production. This article aims to provide an in-depth introduction to the 940nm IR illuminator, its working principle, applications, and the future development trends.

Introduction to IR Illuminator 940nm

The 940nm IR illuminator is a device that emits infrared light with a wavelength of 940 nanometers. It is widely used in various fields due to its excellent performance and low cost. The 940nm IR illuminator has a longer wavelength than the commonly used 850nm IR illuminator, which allows it to penetrate deeper into the object being illuminated, resulting in a better illumination effect.

Working Principle of IR Illuminator 940nm

The working principle of the 940nm IR illuminator is based on the photoelectric effect. When a semiconductor material is exposed to light, it can generate a voltage, which is known as the photoelectric effect. The 940nm IR illuminator uses a semiconductor material, typically gallium arsenide (GaAs), to convert infrared light into electrical energy.

The semiconductor material is encapsulated in a housing and equipped with a lens to focus the infrared light. When the 940nm IR light is emitted from the lens, it can be used to illuminate the target object. The electrical energy generated by the photoelectric effect is then converted into light energy, which is emitted from the illuminator.
