A projector is an optical instrument, which uses optical elements to enlarge the outline of a workpiece and project it onto a screen. The profile can be measured by transmitted light, and the surface shape of blind holes and the surface of parts can also be measured by reflected light. The projector is especially suitable for measuring complex contours and small workpieces, such as clock parts, stamping parts, electronic components, templates, molds, threads, gears and molding tools, with high detection efficiency and convenient use. Widely used in measuring rooms and production workshops, especially for instruments and watches. ?
