IR 980nm 3535 SMD LED Diode

The main difference between 980nm and 850nm infrared (IR) LEDs lies in their wavelength, which affects visibility, illumination distance, camera sensitivity, and application suitability.

Here's a breakdown:

🔍 1. Visibility to the Human Eye

850nm IR LED: Emits a faint red glow that is slightly visible to the human eye, especially in dark environments. This makes it less covert.

980nm IR LED: Appears completely invisible to the human eye. It is more covert, ideal for discreet surveillance.

🎥 2. Camera Sensitivity

850nm: Most standard CMOS or CCD image sensors are more sensitive to 850nm than to 980nm. As a result, 850nm gives brighter and clearer images.

980nm: Has weaker illumination on standard cameras. Some image sensors may have lower sensitivity at this wavelength, resulting in dimmer footage unless specially designed for 980nm.

🌌 3. Illumination Range & Efficiency

850nm: Generally provides better illumination range and clarity, making it more suitable for security cameras, CCTV, and night vision systems.

980nm: Less efficient in terms of range and brightness for standard cameras. However, it's useful when stealth is more important than clarity.

📸 4. Applications

850nm: Used in security cameras, night vision devices, and IR illuminators where performance is prioritized over invisibility.

980nm: Used in covert surveillance, biometric sensors, some industrial and medical devices.
