Introduction to Infrared Light

Infrared light is a form of electromagnetic radiation that has wavelengths longer than visible light but shorter than microwaves. The infrared spectrum is divided into three regions: near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). 830nm infrared light falls within the NIR region, which is generally considered to be between 700nm and 2500nm in wavelength.

Characteristics of 830nm Infrared Light

The 830nm wavelength is particularly interesting due to several characteristics that make it suitable for various applications: 1. Low Absorption in Water: 830nm light has a low absorption rate in water, which makes it ideal for applications where water content needs to be measured or monitored, such as in agricultural, industrial, and medical fields. 2. High Penetration: This wavelength allows for deep penetration into materials, which is beneficial for applications like non-destructive testing and material analysis. 3. Minimal Interference: 830nm light is less susceptible to interference from ambient light, which can lead to more accurate and reliable measurements. 4. Non-Thermal Effects: At this wavelength, infrared light can be used for applications that do not require heating, such as in optical communication and remote sensing.
