The 2022 is the flagship instrument in our line of
alignment telescopes. It is designed specifically to
make measurements of deviations from a reference line, and
secondarily, to provide an extremely
straight optical reference line for any number of alignment
applications. It has two built-in optical micrometers
which measure at right angles to each other. They
allow measurement of lateral shifts perpendicularly from the
line of sight, in both the horizontal and vertical
directions. The 2022 has a
built-in autoreflection target on its objective lens and
includes our model
508 autocollimation illumination unit operating on voltages from 110-220VAC
(photo below).
The 2022 may be purchased without an autoreflection
target by specifying 2022-NAR.
