Description

матизма линзы и стигматора можно использовать дефекты объекта или экрана - это позвол ет осуществить более точное совмещение. Затем в обмотках стигматора измен ют направление электрического тока на противоположное, 3 результате чего направление астигматизма, вносимого стигматором, автоматически и с высокой точностью разворачиваетс  на угол 90° по отношению к направлению астигматизма линзы. Измен   величину электрического тока, проход щего по обмоткам стигматора, полностью компенсируют астигматизм линзы.If a lens or stigmator is used, defects in an object or a screen can be used — this allows for a more precise alignment. Then, in the windings of the stigmator, the direction of the electric current is reversed, 3 as a result of which the direction of astigmatism introduced by the stigmator automatically and with high accuracy is rotated 90 ° with respect to the direction of the astigmatism of the lens. Changing the amount of electric current passing through the stigmator windings fully compensates for the lens astigmatism.
