FIELD: physics.
SUBSTANCE: first by moving the customized elements they are set in accordance with the specified geometric axis and the specified distances between the elements of the optical system. Further, the adjustment errors of this stage are eliminated by moving the adjustable elements relative to the geometric axis in the transverse direction. To do this, pairs of labels are used, on the basis of which the misalignment of the positions of the adjustable elements is determined. Herewith all pairs of optical labels are installed with an angular or radial offset relative to each other.
EFFECT: improving the adjustment accuracy.
