* Pulse conditions : Pulse of f = 10 kHz and duty cycle = 50% modulated
with pulse of f = 0.375 Hz (1.6 s) and duty cycle = 37.5%
Features
High-power output, high-efficiency : PO = 5 mW (typ.)
Fast response and high-speed modulation capability : tr, tf = 20 ns(typ.)
Infrared light emission close to monochromatics light :
λ
P = 880 nm
(typ.)
Narrow directivity using spherical lenses; works well with optical
systems in auto focus systems
