Caution for Handling the Laser Pick-up
The laser pick-up HPC-IC is assembled and precisely adjusted
using a sophisticated manufacturing process in our plant. Do
not disassemble or attempt to readjust it. Please keep the
following instructions carefully in handling pick-up.
1. Handle with Care
(1) Storage
Do not store the pick-up in dusty, high-temperatured or
high-humidity environments.
Please make pick-up faces objective lens upward (pick-up
toward +Z axis direction ) when storage and transport.
(2) Handling
Please take care for preventing from shock by falling down
or careless handling.
2. Laser Diode (LD)
(1) Protect your eyes
The laser beam may damage the human eye, since the
intensity of the focused spot may reach 7 x 10° W/cm? even
if the intensity at the objective lens is 400 pW maximum. As
the light beam spreads after focused through the objective
lens, it does not effect you in the place as far as more than
30 cms. However, do not look at the laser light beam either
through the objective lens directly nor another lens or a
mirror.
{2) Poison of As
Since the LD chip contains As (Arsenic), as GaAs + GaAlAs,
as known as the poison, although the poison is relatively
weak, in comparing with others, e.g.As2O3, AsCls etc., and
the amountis small, avoid putting the chip in acid or an alkali
solution, heating it over 200°C or putting it into your mouth.
(3) Avoid surge current or electrostatic discharge
The LD may be damaged or deteriorated by its own strong
fight if a large current is supplied to it, even if only a short
time.
Since the semiconductor laser may be damaged easy by
electrostatic generating, be careful to avoid the happening
during handling pick-up.
To connect working table using aviodable electrostatic mat
and chassis of this unit to earth line between high resistor
(1MQ extent).
To connect working human wrist attaching least strap to
earth fine between high resistor (1MQ extent).
Be sure that there is no soldering short for avoiding electro-
static damage at this laser pick-up.
3. 2 Axis Actuator
(1) Actuator
The pertormance of the actuator may be effected if magnetic
material is located nearby, since the actuator has a strong
magnetic circuit. Do not permit dust to enter through the
clearance of the cover.
(2) Cleaning the lens
it
may
change
the
specifications
by
attaching
dust
or
ash
or
the
objective
lens.
Clean
the
lens
with
a
cleaning
pape:
dampened
with
a
little
isopropil
alcohol,
not
pressing
lens
with so much strength by the cleaning paper.
4. Metal Bearing
As
the
metal
bearing
of
Cu-compound
sintered
alloy
is
impreg
nated
with
FROIL946P,
never
fail
to
supply
the
bushing
with
the
same
lubricant
at
the
time
of
replacing
the
pick-up.
5. Handling
Please
handle
the
laser
pick-up
with
holding
the
side
base
(rosin
molded
part).
When
either
a
part
of
human
body
or
some
other
things
may
happen
to
touch
directly
with
the
circuit
pant
ot
P.W.Board,
i
may
cause
deterioration,
take
careful
attention
in
handling
this
base.
