Vladimir,

The wire tester I use was built back in 1980.  LEDs were still pretty new
and fairly expensive, but the little "Grain of  wheat " bulbs
were about 4 for a dollar so  I use one of them as my light source. Even
though it was small the light still had to be relayed through a small hole
to a small right angle mirror, thru a ground glass screen, (more of a chip,
really), then out the pinhole. The whole setup attaches to my Foucault
tester by removing the KE and sliding in the wire tester. It measures
1/2" thick x3/4" wide x1" tall with a 1/2" long by
1/4" diameter light source projecting from the left with wires to a 6V
power source and rheostat. The pin hole is 5mm below the center of the wire
aperture.

I will be posting pictures of it and some other "stuff" over on
the Schmidt Camera chat in the next week or so.
