Description
The HL6347MG/48MG 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. The beam has 12 deg offset against the package reference plane. Please take account it mounted on
aboard.
2. The beam divergence has dependence of temperature, if you use this device into your system please check
on it enough before design.
