Using a reflective surface, such things as the differences, variations and deviations of the microscopic edges of the object are read and a wide variety of measurements can be taken concerning deviations in its straightness, perpendicularity, parallelism, flatness and the like. The Autocollimator 6D makes high-precision measurements simultaneously on two axes with the darkfield technique and can be used for measurements like those for a plane mirror with a small surface area.
