Thin gold film on fibre optic cores
--
I wish to gold coat small sections of fibre optic cores.
The process would involve stripping the section of fibre optic
core of its jacket and cladding, then giving it a gold coating of an
even thickness (500 angstroms, about 5 micrometers). I know how to
electroplate metals, but the plastic/glass fibre optic cores are
unknown. I have access to a sputter coating machine, but this would
give an uneven coat, thickening near the gold source.
There are facilities here for some construction of baths etc. and
there are fume cupboards and toxin disposal regimes in place, ie. I
have a safe working environment, and I am able to build small things.
Also we have suppliers for chemicals and basic electronics.
Only solicitations involving equipment that can perform this task
will be appreciated.

Aaron,
I suggest you look to the printed circuit board people in your
country and think about using electroless gold. Two reasons are:
1. Electroless plating systems have been routinely been used for
plated through holes in polymer/glass and polymer/mineral composites
for decades.
2. Electroless coatings in theory are supposed to be uniform re;
thickness.
