FIELD: instrument making.
SUBSTANCE: in a device for fixation and adjusting displacements of an optical part, consisting of a unit of optical part fixation, mechanisms of linear displacement and mechanisms of angular rotations of the optical part fixation unit, mechanisms of angular rotations are installed so that axes of angular rotations are perpendicular and cross in one point, at the same time the unit of the optical part fixation is installed in the device with the possibility of displacement, providing for combination of the optical part top with the point of angular rotations mechanisms axes crossing.
EFFECT: improved efficiency and accuracy of alignment, which is provided due to the fact that displacement units in process of the optical part alignment have independent angular and linear displacements.
