SFH 4713A

The SFH4713A from Osram is an OSLON black series (850nm), 90°, high efficiency, high power infrared emitter. This has low thermal resistance (maximum 18K/W) and superior corrosion robustness. It has 11/15ns rise and fall time of Ie (10% and 90% of Ie max) (IF = 1A, RL = 50 ohm), 1.75V (≤ 2.3V) forward voltage (IF = 1A, tp = 10ms). The total radiant flux is 700mW (IF=1A, tp= 100µs)/685mW (IF=1A, tp= 10ms), temperature coefficient of Ie or Φe (IF = 1A, tp = 10ms) is -0.3%/K, temperature coefficient of VF (IF = 1A, tp = 10ms) is -1mV/K, temperature coefficient of wavelength (IF = 1A, tp = 10ms) is 0.3nm/K. Typical applications include infrared Illumination for cameras, surveillance systems, machine vision systems and eye tracking systems. It is suitable for use in eye tracking, gesture recognition.
