Introduction to IR 940 nm

IR 940 nm refers to infrared radiation with a wavelength of 940 nanometers. This specific wavelength falls within the near-infrared (NIR) spectrum, which is the region of the electromagnetic spectrum just beyond the red end of the visible spectrum. IR 940 nm is widely used in various applications due to its ability to penetrate through some materials and its compatibility with a wide range of sensors and devices.

Characteristics of IR 940 nm

One of the primary characteristics of IR 940 nm is its ability to pass through certain materials, such as glass, water, and some plastics, without significant absorption or scattering. This property makes it ideal for applications where the detection of objects or materials through barriers is required. Additionally, IR 940 nm has a relatively low cost and high power output, making it a cost-effective solution for various applications.

Another significant characteristic of IR 940 nm is its compatibility with a wide range of sensors and devices. Many sensors and cameras designed for IR detection operate in the 940 nm range, allowing for seamless integration into existing systems. Furthermore, IR 940 nm can be easily modulated using laser diodes, making it suitable for applications requiring directional or focused illumination.
