HL6335G/36G
Circular Beam Low Operating Current
ADE-208-1419C (Z)
Rev.3
Mar. 2002
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 wavefront performance is not guaranteed.
3. The beam has 12 deg offset against the package reference plane. Please take account it
mounted on a board.
