3W IR Power Led 904-905nm - 60 Degree Infrared Led

3W 904-905nm High-Power Infrared LED – 60° Lens Integrated (1.4V - 1.6V)

Product Overview:

Deliver precise high-energy infrared output with the 3W 904-905nm High-Power Infrared (NIR) LED. Emitting at the 904nm to 905nm wavelength band, this specialized high-power emitter sits in a key optical spectrum widely utilized for laser rangefinding, optical sensing, velocity measurement, and scientific instrumentation.

Equipped with an integrated 60-degree optical lens, it focuses radiant flux into a tight beam pattern to maximize energy density and projection distance. Designed as a bare emitter, it offers total mounting flexibility for custom PCBs, aluminum heatsink modules, and specialized optical setups.

Key Features:

• Specialized 904-905nm NIR Spectrum: Emits within a critical waveband optimized for optical detectors, silicon photodiodes, and time-of-flight (ToF) sensing applications.
• Focused 60° Optical Lens: Concentrates light output into a 60-degree beam angle to achieve higher irradiance over target surfaces with minimal beam dispersion.
• Low Forward Voltage (1.4V - 1.6V): Efficient electrical profile designed for low-voltage power rails and constant-current drivers.
• 100% Invisible IR Output: Operates entirely outside the visible light spectrum with zero visible red glow, ensuring stealthy and covert operation.
• Bare Emitter Format: Direct thermal connection compatibility for mounting onto external aluminum heatsinks or custom circuit board layouts.

Technical Specifications:

Primary Applications:

• Distance Measurement & Rangefinding: Suitable for optical rangefinders, proximity sensors, barrier detection, and experimental LiDAR setups.
• Machine Vision & Industrial Automation: Used in high-speed optical inspection, barcode reading, object position sensing, and industrial automation control.
• Biomedical & Spectroscopic Sensing: Applied in blood component absorption research, specialized phototherapy experimentation, and optical testing equipment.
• Laboratory & Custom R&D: Ideal for building custom NIR arrays, pulse illuminators, and optical research rigs.

Critical Operating & Safety Guidelines:

• Current-Limiting Circuit Required: Operating at a low forward voltage of 1.4V – 1.6V DC, this LED must be driven using a dedicated Constant Current Driver (600mA–700mA) or a current-regulated circuit. Direct connection to a constant voltage power supply without current regulation will instantly trigger thermal runaway and destroy the chip.
• External Aluminum Heatsink Required: High-power 3W LEDs generate significant localized heat. The emitter must be mounted directly onto an adequate external aluminum heatsink using thermally conductive adhesive or thermal paste prior to applying power.
• Invisible Radiation / Eye Safety: Light output at 904nm–905nm is completely invisible to the human eye, but high-intensity infrared energy is being emitted. Do not look directly into the lens when powered on. Use an IR-sensitive camera or sensor card to check operation, and wear proper infrared safety goggles during testing.
