DL-3149-054
Index Guided AlGaInP Laser Diode
Overview
DL-3149-054 is 670 nm (Typ.) index guided AlGaInP laser diode with low
threshold current and high operating temperature. The low threshold
current and high operating temperature are achieved by the use of a
strained multiple quantum well active layer. DL-3149-054 is suitable for
applications such as bar-code scanners, laser pointers and other optical
information systems.
Features
•Short wavelength : 670 nm (Typ.)
•High operating temperature : 5 mW at 60°C
•Low threshold current : Ith = 30 mA (Typ.)
•Small package : 5.6 mmØ
