Infrared Light Emitting Diodes
LN189M
GaAlAs Infrared Light Emitting Diode
Unit: mm
Light source for distance measuring systems s Features
• High-power output, high-efficiency: PO = 5.5 mW (typ.) • Fast response and high-speed modulation capability: tr, tf = 20 ns (typ.) • Infrared light emission close to monochromatic light: λP = 880 nm (typ.) • Narrow directivity using spherical lenses; works well with optical systems in auto focus systems
