Introduction to 940nm IR Light

940nm IR light, also known as near-infrared light, falls within the infrared spectrum, which is just beyond the visible light range for humans. This specific wavelength is particularly favored due to its ability to penetrate various materials without causing damage. The 940nm IR light is often used in applications where deep penetration and non-invasive sensing are required.

Properties of 940nm IR Light

The properties of 940nm IR light make it a versatile choice for numerous applications. Here are some key characteristics: - Penetration Depth: 940nm IR light has a relatively high penetration depth, which allows it to pass through materials like skin, clothing, and some plastics without significant absorption. - Non-Damaging: Unlike higher energy forms of light, such as ultraviolet or X-rays, 940nm IR light is non-ionizing and does not cause damage to living tissues or materials. - Wavelength: The 940nm wavelength is near the lower end of the infrared spectrum, making it less likely to be absorbed by atmospheric gases and more likely to travel long distances. - Bandwidth: 940nm IR light has a broad bandwidth, which means it can carry a significant amount of information, making it suitable for high-speed data communication.
