HL6740FG
Dual Beam Visible Laser Diode
ODE-208-024 (Z)
Rev.0
Feb. 24, 2006
Description
The HL6740FG is a 0.67 µm band AlGaInP laser diode with a multi-quantum well (MQW) structure. It is an array of
two individual beams on one chip. Therefore, it is suitable as a light source for a high-speed printer, such as PPC and
LBP, and so on.
Features
⢠Continuous operating output to each beam: 5 mW CW
⢠Visible light output: 675 nm Typ
⢠Difference of wavelength between 2 beams
: 3 nm Max
⢠Low threshold current: 35 mA Typ
