FIELD: instrumentation.SUBSTANCE: device for positioning the object comprises the means for angular orientation, consisting of the fixed and movable parts, and the means for vertical supplying, connected to the movable part of the means of angular orientation. The means for angular orientation provides the angular orientation of the object relative to two intersecting mutually perpendicular horizontal axes and can be made in the form of a spherical hinge. The means of vertical supplying provides the movement of the object relative to the movable part of the means of angular orientation along the vertical axis and can be made in the form of a linear electric motor or piezo-drive actuator.EFFECT: finding the tested fragment of surface at the focus of the lens while carrying out the angular orientation of objects of different thicknesses.8 cl, 6 dwg |
