Metallographic microscope useful for the characterization of conductors drawing dies

摘要

A metallographic microscope for characterizing conductor drawing dies having a light collimating system, linear scales for horizontal and vertical axis of the platina, a positioning device on the platina, an electronic closed loop circuit for controlling the illumination through the collimating system, and a power supply and internal cabling within the body of the microscope for a video camera mounted to the lens system.
