Description
The HL6335/36G 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.
