Autocollimator with 90°-viewing is also available with mechanical double micrometer (AKR MD). This type AKR MD is used if a straight viewing autocollimator cannot be used from ergonomic point of view. It allows the measurement of tilting angles in two directions. The lateral movement of the eyepiece reticle in x- and y-direction in the mage plane can be read from the scale of the micrometers. The scale division is 5 micrometer. Note: A version with a programmable measuring gauge (MDD) is not available because of mechanical limititation.
