SAFETY INFORMATION ON THIS PRODUCT
Warning
Laser Beam
A laser beam is emitted from this diode during operation.
The laser beam, visible or invisible, directly or indirectly, may cause injury to the eye or loss of
eyesight.
• Do not look directly into the laser beam.
• Avoid exposure to the laser beam, any reflected or collimated beam.
Caution GaAs Products
This product uses gallium arsenide (GaAs).
GaAs vapor and powder are hazardous to human health if inhaled or ingested, so please observe the
following points.
