Osram SFH4555 - High speed high power 850nm 5mm IR LED (infrared emitter) - 850nm 5 mm LEDs infrared, ROHS. Like Osram SFH4556, but with narrower viewing angle and higher radiant intensity.

Technical data:

Peak wavelength 850 nm,
viewing angle 10 degrees (±5°),
radiant intensity group CW (bin 1): ≥250 mW/sr (typ. 500 mW/sr) at 100 mA, 2000 mW/sr at 1 A,
total radiant flux 50 mW,
forward current 100 mA, surge current 1.5 A,
forward voltage 1.5 V / <1.8 V (at 100 mA), 2.4 V / <3.0 V (at 1 A),

• Sensor technology;
• Data transmission;
• Real-time 3D CMOS-based digital imaging;
• Discrete optocouplers.

Safety Advices, Warning:

Depending on the mode of operation (drive current, pulse duration, optics etc.), these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 60825-1 and IEC 62471. Class III B laser-like product. When operating powerful emitters, care should be taken to comply with IEC to minimize any possible eye hazard:

- Use lowest possible drive level.
- Use diffusing optics where posiible.
- Avoid staring into powerful emitters or connected fibers.
- Don't look into beam! Invisible radiation.
