8665 Rotating Scale Holders

For axial orientation of a scale in our Invar System

Have you ever needed to see the targets at both ends of an
Invar stack at the same time? We have - especially
when calibrating a theodolite system using scales or
calibration targets such as our 564W-CE. That's
why we designed the 8665 - a scale holder with a
knurled lock knob on the base. Loosen the knob,
and you can rotate the upper portion of the scale holder
to the axial angle needed to match the orientation of
the fixed scale holder on the other end.
The 8665 Series also incorporates our new "squeeze" lock
scale holder clamp. This improved scale mounting
clamp has a movable jaw which moves laterally from the
side to firmly clamp the scale. The scale holder
will work with all of our old and new style scales, as
well as all older Cubic Precision (K+E) scales.
The 8665 Series comes in both English and metric units -
see the table below for the effective lengths of each.

[*Effective length is the distance from
the bottom interface surface of the scale holder, which mates with the
end of the Invar tubing, to the top interface surface, on which rests the
bottom of the scale.]
