I had a go today but failed , any ideas? A violinist, I know, asked
about
such an inspection viewer, small and flexible.
My attempt started with a clump of plastic optical fibres from one of
those
lamps with a rotating colour wheel and epoxyied into a lump on the lamp
end.
And a dome cut from the top of a clear lens LED. Both ground down ,
finer
grit, until toothpaste on paper. LED , as a fish-eye lens, sort of
focused
the sun at about 5mm so focal length 5mm. Tried fixing lens 5mm and then
10mm from the ground fibres surface and blanked off remaining area.
The other free ends of the fibres grouped as they came so not fully 1:1
mapping but no change of image viewing when moving over a black and
white
grid. Any ideas , or a total waste of time. The fibres are coarse 10
thou
diameter , but just giving it a go.


You could buy one of these if you had enough work to justify one.

How about something using a miniature camera innards mounted on a mini
gooseneck if it doesn`t have to be steerable?

How small ? without going into 007 territory, do you reckon the lens plus
CCD is (assuming this is separatable and can be extended) for a standard
webcam or CCTV camera.
I did do similar, ages ago, to make a printing microfiche viewer by
extending a standard fax CCD out to under an illuminated fiche viewer
