Application Guide
Infrared LEDs for Facial Recognition & Biometrics
Stable NIR illumination for 2D/3D facial mapping, iris scanning, and secure access systems that need consistent performance across environments.
Key needs
- Consistent illumination for depth/IR cameras in varied ambient light
- Avoiding import/tariff delays with domestic supply
- Balancing eye safety, covert operation, and sensor sensitivity
Recommended wavelengths
Evaluate these options and compare output in the visualizer and charts.
Where these LEDs are used
2D/3D facial recognition cameras
Iris/eye tracking modules
Access control & smart locks
In-cabin driver monitoring (DMS)
FAQs
Which wavelength should I choose for facial recognition?
850nm maximizes most sensor response; 940nm reduces visible glow for more covert operation. Many systems prototype with both.
Are these LEDs eye-safe?
Designs must follow IEC eye-safety limits. Our bare die LEDs support controlled drive currents; final system compliance depends on optics and drive conditions.
How fast can you deliver samples?
Standard lead times are ~3 weeks; contact sales for samples and current availability.
Next steps
Compare wavelengths in the 3D visualizer and charts, then request samples to validate your design.
