Typ MITSF The MITSF machine is designed to identify and print progressive and multifocal semi-finished lenses. The PPOS system, integrated in the unit, detects the μ-engravings or the upper segment line and identifies the semi-finished by reading the identification code (check of product code, Addition, base, eye, logo at the edge or under the μ-engravings) by Optical Character Recognition. The inspected lenses are then inked by a robot, permitting a large flexibility in image choice (10 plates – 20 images). The data of this machine can be transmitted to the automatic packaging unit (MESF), eliminating any product mispack.
