LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER: 5 mw

WAVELENGTH: 780 – 785 nm

Additional Laser Caution

1. Laser Interlock Mechanism

The position of the switch (S1) for detecting loading

completion is detected by the system microprocessor, and

the design prevents laser diode oscillation when the switch

is not in LPS1 terminal side (when the mechanism is not

clamped and LPS1 signal is high level.) Thus, the interlock

will no longer function if the switch is deliberatery set to

LPS1 terminal side. ( if LPS1 signal is low level ).

∗

In the test mode

the interlock mechanism will not function.

Laser diode oscillation will continue, if pin 33 of CXA1782CQ

(IC101) on the MOTHER BOARD ASSY is connected to

GND, or pin 43 of IC701 (LDON) is connected to low level

(ON), or else the terminals of Q101 are shorted to each

other (fault condition).

2. When the cover is opened, close viewing of the objective

lens with the naked eye will cause exposure to a Class 1

laser beam.
