Measuring range and measuring distance
The measuring range of any autocollimator decreases with increasing measuring distance. The measuring accuracy of autocollimators is distance-dependent, negating environmental influences. With the autocollimators of the ELCOMAT® series, the measuring range remains constant up to a certain measuring distance and then decreases with increasing distance between the autocollimator and the mirror. The typical measuring range at different distances is listed in the technical specifications of the ELCOMAT® 5000.
