Semiconductor Laser for LBP(Laser Beam Printers)
Overview
The LNC703PS is a near infrared GaAlAs laser diode which
provides continuous oscillation in single mode and is stable at low
operating current. This product is characterized by a low operating
current and low drooping, making it suitable for a wide range of
optical information equipment.
Features
Low current operations : 40 mA (with 12 mW output)
High output (15 mW) for increased printing speed
