3W 760-770nm High-Power Infrared LED – 60° Lens Integrated (1.7V - 1.9V)
Product Overview:
Deliver precise optical energy with the 3W 760-770nm High-Power Near-Infrared (NIR) LED. Emitting in the deep near-infrared spectrum (760nm – 770nm), this specialized high-power emitter is widely used in medical research, biological phototherapy, optical sensing, and scientific instruments.
Featuring an integrated 60-degree optical beam lens, this LED focuses emitted radiation into a concentrated beam, delivering higher power density and deeper target illumination. Designed as a bare emitter, it allows complete integration versatility for custom PCB layouts, arrays, and optical modules.
Key Features:
- Deep Near-Infrared Spectrum (760-770nm): Emits within a key NIR optical window known for deep biological tissue penetration and specialized optical absorption.
- Phototherapy & Medical Applications: Ideal for photobiomodulation (PBM), deep-tissue therapy devices, vascular imaging research, and biomedical treatment systems.
- Focused 60° Optical Lens: Directs light output tightly to maximize irradiance and reduce power loss over distance.
- Ultra-Low Forward Voltage (1.7V - 1.9V): Highly energy-efficient electrical profile designed for low-voltage power supplies and custom driver circuits.
- Flexible Bare Emitter Format: Direct mounting compatibility with external thermal heatsinks and custom circuit designs.

- Machine Vision & Night Illumination: Ideal for specialized camera lighting systems, covert night vision enhancement, and industrial inspection modules.
- Laboratory & Custom R&D: Perfect for prototyping specialized NIR light engines and optical instruments.
Critical Operating & Safety Guidelines:
- Current-Limiting Circuit Required: Operating at a low forward voltage of 1.7V – 1.9V DC, this LED must be driven using a constant current driver (600mA–700mA) or an appropriate current-limiting circuit. Connecting directly to a constant voltage source without current regulation will instantly ruin the emitter due to thermal runaway.
- External Aluminum Heatsink Required: High-power 3W LEDs convert significant energy into localized heat. The LED must be installed directly onto a suitable external aluminum heatsink with thermal paste or thermally conductive adhesive prior to powering on.
- Invisible Radiation / Eye Safety: Light output at 760nm–770nm is mostly invisible to the human eye, but high radiant flux is being emitted. Do not look directly into the beam while operational. Wear proper infrared safety eyewear when handling and testing powered devices.
