This article aims to provide an in-depth introduction to 810 nm infrared LEDs, covering their characteristics, applications, and market trends.

Introduction to 810 nm Infrared LEDs

810 nm infrared LEDs are a type of infrared LED with a peak emission wavelength of 810 nm. They belong to the near-infrared spectrum, which is located between visible light and mid-infrared. Compared with other infrared LEDs, 810 nm infrared LEDs have several advantages, such as longer wavelength, lower cost, and higher efficiency.

Characteristics of 810 nm Infrared LEDs

1. Longer Wavelength

810 nm infrared LEDs emit light at a longer wavelength compared to other infrared LEDs. This longer wavelength allows the light to penetrate deeper into materials, making it suitable for various applications, such as thermal imaging and non-contact temperature measurement.

2. Lower Cost

Compared with other infrared LEDs, 810 nm infrared LEDs are more cost-effective. This is because the manufacturing process of 810 nm infrared LEDs is relatively simple, and the raw materials are more abundant. As a result, the cost of 810 nm infrared LEDs is lower, which makes them more accessible to a broader range of applications.

3. Higher Efficiency

810 nm infrared LEDs have higher efficiency compared to other infrared LEDs. This is because the longer wavelength of 810 nm infrared LEDs allows for better light extraction and lower heat generation. As a result, 810 nm infrared LEDs can achieve higher brightness and longer lifespan.

Applications of 810 nm Infrared LEDs

1. Thermal Imaging

Thermal imaging is a technology that uses infrared radiation to detect and measure the heat emitted by objects. 810 nm infrared LEDs are widely used in thermal imaging applications due to their longer wavelength and better penetration ability.
