FIELD: measurement equipment.
SUBSTANCE: device comprises a source of white light (1) in the form of an LED-strip (40), a collimation unit (4), a unit of a spectrometer for splitting of a white light beam (30) into a beam of multichromatic light (31), sent to a tested item (5) at the specified fall angle, and a chamber (3) for recording of the reflected beam of monochromatic light (32), so that information on the height of the surface along the axis z of the tested item (5) may be extracted from the value of the shade of the reflected beam (32) with relative displacement of the tested item (5) in direction (9) of scanning along the axis x. At least one microlens (41) is optically connected with at least one LED for preliminary straightening of the specified beam of white light (30). The collimating unit (4) is made as capable of collimation of the specified beam (30) of white light by 360° with collimation quality of 2° or less and formation of a tape beam of white light perpendicular to the scanning direction (9). The device comprises at least one lens (42, 43, 44, 45), preferably a cylindrical lens (42), and at least one aperture facility (50), preferably the controlled aperture of the slot membrane.
EFFECT: capability to measure item surface and to monitor paste for soldering with tinning melt, creation of a 3D-model of item surface.
