SMT IR emitter is very ‘bright’

Aimed for use in proximity sensors, touch displays, and light barriers where space is limited, the Mini Midled SFH 4451 IR emitter is only 2.3 x 1.95 x 0.9 mm, yet it provides a narrow beam (half-angle of 17°) with the highest radiant intensity of any device its size: 60 mW/sr at 100 mA.

The device is designed for surface mounting and its non-metalized surfaces are dark colored so it can be mounted inconspicuously behind a smartphone cover. It produces an 850-nm-wavelength output and uses a metalized reflector which is said to considerably reduce optical crosstalk, so no optical shielding is required.
