Hi,
I just acquired a red laser pointer. Unfortunately it needs reassembly.
It's the type that takes three button batteries and has a little round press
button on the side of its metal housing. It fits on a keyring and came with
twelve screw on tips.
Anyway, I tightened a tip a little too much and this moved the whole
assembly around in the case so that the switch did not line up with the
press button anymore. I tried to rotate the assembly from the battery end
with a small tool and the innards fell out.
Looking down the tube to the back of the lens stuff is a slot cut offset
across the circle of the lens housing.
There is two tiny boards, one has a spring for battery contact, the switch,
an smd component and a square area of silvery coloured metal plating top and
bottom at opposite end to battery spring. The smd component connects to one
plate but the other plate has no contact with anything on this board.
The other board has what I assume is the laser diode mounted on it. It is
about the size of a grain of salt and is attached to a bronze looking metal
plate one side of the board. This tiny part (or diode?) has a wire going to
a silvery looking plate on the opposite side of the board.
Now, please, if above is enough information to identify what I mean, I would
be very grateful for advice on how to put this back together.
Thanks,
David
