Whether you're building a surveillance array or a research-grade optical setup, this module provides reliable, consistent near-infrared output in a rugged, compact housing.

Key Features

• Adjustable Focus Optics: Fine-tune the spot diameter at 1M distance to ≤5mm — ideal for precision targeting and controlled illumination fields.
• 785nm Wavelength (775–790nm ±): Near-infrared output invisible to the naked eye, perfect for covert night vision and IR-sensitive camera systems.
• High Output Power: 800mW–3000mW (0.8W–3W) output power suits everything from low-light enhancement to demanding industrial imaging.
• Wide Working Voltage: Operates on 8.5–12V DC, compatible with standard 12V power supplies.
• Continuous Excitation Mode: Designed for uninterrupted, always-on operation with a start time of ≤0.01 seconds.
• Long Service Life: Rated for over 6,000 hours of operation, reducing replacement frequency and maintenance costs.
• Broad Temperature Range: Working temperature of -10°C to +40°C and storage range of -40°C to +80°C make it suitable for indoor and outdoor deployments.
• Simple Wiring: Red = positive, Black = negative. TTL-compatible option available (yellow = positive supply, negative).
• Compact Form Factor: Available in 33×33×105mm or 40×40×105mm housing — easy to integrate into custom builds and existing systems.

Frequently Asked Questions

Q: What is the difference between the 785nm wavelength and standard visible LEDs?

A: The 785nm wavelength falls within the near-infrared (NIR) spectrum, which is invisible to the human eye but detectable by NIR-sensitive cameras and sensors. This makes it ideal for covert night vision illumination, where you want a camera to "see" in the dark without producing visible light that would alert subjects or disrupt environments.

Q: Can this 785nm NIR LED module be used with a standard 12V power supply?

A: Yes. The module operates on a DC voltage range of 8.5V to 12V, making it fully compatible with widely available 12V DC power supplies or adapters. Ensure your power source can supply sufficient current for the selected output power level (up to 3W / 3000mW).

Q: Is the focus adjustable after installation?

A: Yes. The module features adjustable focus optics, allowing you to fine-tune the infrared beam spot diameter — achieving ≤5mm at 1 meter distance. This flexibility makes it suitable for both wide-area illumination and precision spot targeting in imaging and inspection setups.

Q: What does TTL wiring mean for this module?

A: TTL (Transistor-Transistor Logic) wiring allows the module to be switched or modulated by a digital control signal from a microcontroller or driver board. When using the TTL option, connect Yellow to the positive supply and Black to negative, enabling programmatic on/off or pulsed control of the NIR output.
