RLD-78MA
The RLD-78MA is world’s first mass-pro-
duced laser diodes that is manufactured
by molecular beam epitaxy. The signal-
to-noise ratio is stable in comparison to
conventional manufacturing techniques.
This device is ideal for use in compact
disc players.
FExternal dimensions (Units: mm)
FApplications
Compact disc players
FFeatures
1) Signal-to-noise ratio guaranteed
over entire operating temperature
range.
2) Reduced facet reflection.
3) One-third the dispersion compared
with conventional laser diodes.
4) High-precision, compact package.
