Probe Disassembly
It may be necessary to remove the outer lens barrel from the fiber optic bundle for mounting. Follow
these instructions. (Instructions apply only to the probe type shown.)
1. Note the knurled collar. To remove the
lens barrel, unscrew the knurled collar.
2. As the knurled collar is loosened, be
sure to support the lens barrel. Do not
let it drop.
3. When the knurled collar is disengaged
from the lens barrel, slide the lens barrel
off over the fiber optic bundle end.
The knurled collar is captured, and will
not fall off. Do not use the set screws –
the knurled collar sets the gap, and the
set screws will interfere with that
setting.
4. To re-assemble, gently insert the fiber
optic bundle end into the lens barrel.
Fully tighten the knurled collar onto the
lens barrel. Hands tighten; do not use
tools. Internal spacing between the lens
and the fiber optic bundle end is
automatically set using this method.

from the “snap-ring” side.
