HL6312/13G
AlGaInP Laser Diodes
Description
The HL6312/13G are 0.63 µm band AlGaInP laser diodes with a multi-quantum well (MQW)
structure. Wavelength is equal to He-Ne Gas laser. They are suitable as light sources in bar code
readers, laser levelers and various other types of optical equipment. Hermetic sealing of the package
achieves high reliability.
