Features
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.
