Optical Communication 850nm infrared LEDs are widely used in optical communication systems, such as fiber optic networks and wireless communication. These LEDs emit light that is transmitted through fiber optic cables or air, enabling high-speed data transmission. The 850nm wavelength is preferred in optical communication due to its low attenuation and compatibility with existing infrastructure. 3. Biometric Authentication In recent years, biometric authentication has become increasingly popular for securing access to sensitive information and facilities. 850nm infrared LEDs are used in biometric systems to capture the unique patterns of an individual's fingerprint, face, or iris. The near-infrared spectrum provides better contrast and resolution, leading to more accurate and reliable authentication. 4. Industrial Automation 850nm infrared LEDs are also used in industrial automation applications, such as barcode scanners, optical sensors, and proximity sensors. These devices rely on the infrared light emitted by the LEDs to detect and measure various parameters, such as distance, position, and speed. The 850nm wavelength is suitable for these applications due to its high sensitivity and low cost. 5. Medical Imaging In the medical field, 850nm infrared LEDs are used in various imaging techniques, such as photoacoustic imaging and fluorescence imaging. These LEDs emit light that is absorbed by specific tissues or molecules, allowing for the visualization of internal structures and biological processes. The near-infrared spectrum is particularly useful for medical imaging due to its ability to penetrate tissue and minimize harm to the patient.
