Electronic autocollimators are widely used in mechanical engineering to measure the straightness/parallelism of machine beds, to measure the pitch and yaw movements of machine axes and to determine the positional uncertainty of rotary and dividing tables. The new ELCOMAT vario N product line of electronic autocollimators from MÖLLER-WEDEL OPTICAL GmbH is the logical further development of the ELCOMAT® vario D product line, which has proven itself worldwide.
