3535 Infrared LED Bead | 900-1700nm IR Emitter Tube with 20mm Aluminum Substrate

Our 3535 infrared LED emitter is built for high-performance infrared optical applications. It comes pre-soldered on a 20mm aluminum substrate to improve heat dissipation and simplify installation. Multiple beam angles are available: 30°, 60°, 120°. Peak wavelength range: 980nm ~ 1520nm (spectral range: 900-1700nm).

Electro-Optical Characteristics

Test condition: IF =700mA, Ta = 25°C, RH 60%

• Radiometric Power tolerance: ±7%

• Forward voltage tolerance: ±0.1V

• Peak Wavelength tolerance: ±5nm

• Spectral Half Width tolerance: ±5nm

• Radiometric power is tested at the peak of spatial radiation pattern, which may not coincide with the mechanical axis of the LED package

• Radiometric power data is for reference only

• 2θ₁/₂: The off-axis angle where radiant intensity drops to 1/2 of peak intensity

• Thermal resistance: RthJS (Junction to Solder)

• Pulse current condition: Pulse Width ≤100μs, Duty cycle ≤1/10

Important Notes

• LED performance will deviate from the listed specs if operating outside the rated parameter range. Please ensure power dissipation never exceeds the absolute maximum rating.

• All tests are completed under standardized LumiSee LED test environment.

• Ideal for infrared detection, machine vision, optical sensing, biometric recognition, surveillance supplementary lighting and other optoelectronic systems.
