IR illuminator 940nm has become an essential component in the field of infrared imaging technology. As the name suggests, this type of illuminator emits light at a wavelength of 940 nanometers, which falls within the near-infrared spectrum. This technology has found wide applications in various industries, including security, medical, scientific research, and automotive. In this article, we will explore the history, working principle, applications, and future prospects of IR illuminator 940nm.

History of IR Illuminator 940nm

The concept of infrared imaging dates back to the early 20th century when scientists began to explore the use of infrared radiation in various applications. However, it was not until the 1940s that the first practical infrared illuminator was developed. Over the years, the technology has evolved, and today, IR illuminator 940nm is widely used in various industries.

Working Principle of IR Illuminator 940nm

IR illuminator 940nm works on the principle of emitting near-infrared light, which is invisible to the human eye. The illuminator consists of a light source, a lens, and a filter. The light source emits light at a wavelength of 940nm, which passes through the lens and is focused onto the target. The filter ensures that only the desired wavelength is emitted, making it suitable for specific applications. The near-infrared light emitted by the illuminator is absorbed by objects, and the reflected light is then captured by the infrared camera or sensor. The camera converts the reflected light into an electrical signal, which is then processed to produce a clear image. The 940nm wavelength is particularly useful for night vision applications, as it can penetrate smoke, fog, and dust, providing clear images even in low-light conditions.

Applications of IR Illuminator 940nm

1. Security: IR illuminators are widely used in security cameras for night vision and surveillance purposes. The 940nm wavelength allows for clear images in low-light conditions, making it an ideal choice for security applications. 2.
