ETC HL6501MG

HL6501MG
Visible High Power Laser Diode for DVD-RAM
ADE-208-515H (Z)
9th Edition
Dec. 2000
Description
The HL6501MG is a 0.65 µm band AlGaInP laser diode (LD) with a multi-quantum well (MQW) structure.
It is suitable as a light source for large capacity optical disc memories, such as DVD-RAM, and various
other types of optical equipment.
Hermetic sealing of the small package (φ5.6 mm) assures high reliability.
