DL-3147-041
No.5862 1/3
Overview
DL-3147-041 is index guided 645 nm (Typ.) AlGaInP laser diode with low
threshold current and high operating temperature. The low threshold current
and high operating temperature are achieved by a strained multiple quantum
well active layer. DL-3147-041 is suitable for applications such as bar-code
reader, optical disc systems and other optical information systems.
