HL6343G/44G  
Circular Beam Low Operating Current  
ODE-208-018 (Z)  
Rev.0  
Jul. 01, 2005  
Description  
The HL6343G/44G are 0.63 µm band AlGaInP laser diodes can be operated with low operating current. These products  
were designed by self aligned refractive index (SRI) active layer structure. These are suitable as a light source for laser  
levelers, laser scanners and optical equipment for measurement.

Notes: 1. Care must be taken in laser diodes handling to prevent optical damage caused by forward surges as well as  
by ESD.  
2. The beam has 12 deg offset against the package reference plane. Please take account it mounted on a  
board.
