Description
руемых поверхностей, сначала плоское зеркало устанавливают в положение на оси, соответствующее разности зональных фокусных рассто ний, затем перемещают его до совпадени падающих и отраженных от контролируемой поверхности пучков лучей, и по величине перемещени суд т об отклонении формы контролируемой поверхности.first, a flat mirror is positioned on an axis corresponding to the difference in zonal focal lengths, then it is moved until the beam of rays falling and reflected from the test surface coincides, and the displacement of the test surface is judged by the displacement.
