In the automotive industry, infrared LEDs 850nm are used for various purposes, such as reverse parking sensors, automotive lighting, and driver monitoring systems. The longer transmission distance and higher intensity of 850nm infrared LEDs make them suitable for these applications. For instance, in reverse parking sensors, 850nm infrared LEDs can detect obstacles effectively, providing a safe driving experience for drivers.

3. Medical

In the medical field, infrared LEDs 850nm are used for applications such as medical imaging, biometric authentication, and endoscopy. The compatibility of 850nm infrared LEDs with human skin and their ability to penetrate tissues make them ideal for these applications. For example, in biometric authentication, 850nm infrared LEDs can scan the vascular patterns on a person’s finger, ensuring accurate and secure authentication.

4. Industrial

In the industrial field, infrared LEDs 850nm are used for applications such as machine vision, thermal imaging, and non-contact temperature measurement. The high intensity and long transmission distance of 850nm infrared LEDs make them suitable for these applications. For instance, in machine vision, 850nm infrared LEDs can provide clear images of objects, enabling efficient and accurate detection.

Advantages of Infrared LEDs 850nm

1. Longer Transmission Distance

Compared with other infrared LEDs, 850nm infrared LEDs have a longer transmission distance. This is because the wavelength of 850nm is closer to the peak of the infrared spectrum, which results in better transmission through materials such as air, glass, and plastic.

2. Higher Intensity

850nm infrared LEDs have higher intensity than other infrared LEDs, which makes them more suitable for applications that require strong light. This is due to the fact that 850nm infrared LEDs have a higher quantum efficiency, which means they can convert more electrical energy into light energy.

3. Compatibility with Human Skin

850nm infrared LEDs are compatible with human skin, which means they can be used for applications that require contact with the skin, such as biometric authentication. This is because the wavelength of 850nm is close to the peak of the human skin’s infrared absorption spectrum, ensuring minimal skin irritation.
