A system and method for positioning a product

The invention relates to a system for locating product, comprising for supporting the card (71), support of the product the card (71) is station (79) and a support wherein the path station (79) is base (72). The card (71) can is opposite to the path station (79) along the first direction X (80), and groove (79) can is opposite to the fixed base along the second direction Y (81) for. The system further - comprising at least one for measuring card (71) is opposite to the fixed base (72) of the laser interferometer (73,74,75,76,77,78). The laser interferometer's major component (73,74,75,76,77,78) is adhered component is floater provided with a groove station (79), so the major device capable of measuring card (71) on the reflector (83,84,85) and fixing base (72) is reflector (82,87) is distance.
