Introduction to 850 nm Infrared

The 850 nm infrared, also known as near-infrared (NIR), is a part of the electromagnetic spectrum that lies between visible light and mid-infrared wavelengths. This specific wavelength is of particular interest due to its unique properties and applications. The 850 nm infrared region is characterized by its ability to penetrate certain materials and surfaces, making it ideal for various imaging and sensing applications.

Properties of 850 nm Infrared

One of the key properties of 850 nm infrared is its ability to be transmitted through materials such as glass, water, and some plastics. This property makes it highly suitable for applications where the detection of objects or substances through barriers is required. Additionally, 850 nm infrared has a relatively low water absorption rate, which allows for better signal transmission in environments with high humidity.

Applications in Security and Surveillance

The 850 nm infrared technology has found extensive use in security and surveillance systems. Infrared cameras equipped with 850 nm sensors are capable of capturing images in low-light or dark conditions, providing clear visibility even in complete darkness. This feature is particularly valuable in areas where covert monitoring is necessary, such as in border control, airports, and critical infrastructure protection.
