Toolmaker’s microscopes and measuring microscopes differ from standard microscopes in one unique way–their ability to measure via a movable microstage, which allows the workpiece to be moved under the optics system. A measuring device (mike heads or DRO system) can measure the microstage travel while the operator moves the workpiece below a crosshair in the optics system from one feature to another. The Mitutoyo toolmaker’s microscope also has a built-in protractor for measuring feature angles. Measuring microscopes are the big brother of toolmaker’s microscopes. They generally have larger stages and options for video systems.
