HL6343G/44G
Circular Beam Low Operating Current
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.
