Application Guide
Infrared LEDs for LiDAR, Time-of-Flight & Depth Sensing
NIR emitters for LiDAR, time-of-flight (ToF), and depth cameras that need controlled peak wavelength, pulsed drive, and reliable domestic supply.
Key needs
- Matching emitter peak wavelength to filter and sensor stack
- Pulsed drive and thermal design for high peak power
- Avoiding import delays on safety-critical automotive and robotics programs
Recommended wavelengths
Evaluate these options and compare output in the visualizer and charts.
Where these LEDs are used
Solid-state LiDAR and rangefinders
Time-of-flight depth cameras
Automotive ADAS sensing (program-specific)
Robotics obstacle detection
Industrial distance measurement
FAQs
Why is 905 nm common in LiDAR?
Many LiDAR and ToF systems target ~905 nm to balance atmospheric transmission, detector availability, and eye-safety planning. Validate exact peak wavelength against your optical filter and sensor.
Does MANULED offer a 905 nm bare die?
Yes. IR905 is part of the MANULED wavelength family. See the product page, charts, and datasheet for electrical and optical specs.
Can these dies be pulsed for ranging?
Drive conditions must stay within datasheet absolute maximums and your thermal design. Contact sales for pulsed-use discussions and sample availability.
Next steps
Compare wavelengths in the 3D visualizer and charts, then request samples to validate your design.
