From CD to DVD
ROHM developed the visible (650 nm) laser diode for Digital Video Disc (DVD) applications.
Well established ROHM's mass-production technology and knowledge with CD/CD-ROM leads the successful
manufacturing process of the DVD laser diodes.

For Laser Beam Printers RLD-78PP-G1, RLD-78NP-G1, RLD-78NP10-G1
This is specifically designed for laser beam printer (LBP) application in a small 5.6 mm diameter package and has
low "droop" characteristics. Typical droop is 5% which is very low and it will assist improving the print quality.
10 mW model RLD-78NP10-G1 is available for high speed printing requirement.

Laserpointers
RLD-65NE is the red laser diode for laser pointer. The laser beam is easily focused to small spot of parallel beam
by single lens and the beam has excellent brightness. RLD-65NE has negative type polarity, so it can be driven with
general drive circuit. RLD-65NE has low operating current, so it's adequate for battery drive.

Product Designation
When ordering, specify the part number.
Check each code against the tables shown below.
Fill in from the left, leaving any extra boxes empty on the right.
This is a general designation. For further information consult your local ROHM representative.
Safety
The light emitted from laser diodes, while almost
invisible to human eye, can cause retinal damage
if viewed directly. Never look directly into the laser
beam or through any lenses or fibers when the
system is operating.
For optical axis alignment or other operations,
we recommend the use of an infrared-sensitive
camera (ITV) or wearing protective goggles.
Notes
The product described in this specification in designed to be used with ordinary electronic equipment or devices
(such as audio-visual equipment, office-automation equipment, communication device, electrical appliances, and
electronic toys). If you intend to use this product or device which require an extremely high level of reliability and
malfunction of which would directly endanger human life (such as medical instruments, transportation equipment,
aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devices), please be sure to
consult with our sales representative advance.
