2024 Alignment Telescope (Metric)


Ships in 4 Weeks

The 2024 is the metric version of 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 2024 has a built-in autoreflection target on its objective lens and includes our model 509 autocollimation illumination unit (see photo below).
For additional general information about this instrument, read about our alignment telescopes. See also similar instrument 2022 (English units).
Fully erect image; diopter scale. Right-angle eyepiece and complete projection accessories available.

Optical micrometer:
  • Built-in horizontal and vertical optical micrometers
  • Displacement: ± 1.2 mm, direct reading to 0.02 mm
  • Accuracy: ±0.010 mm over full range
  • Scale graduations are red and black to indicate direction of displacement
