Microinspection station MK-3, MK-3T

English MainProductsMicroscopyMaterial Science › MK-3, MK-3T

The microinspection station is an inspection and measurement system based on the MI-1 microscope. It is intended for inspection and measurement of structure, composition and properties of metals and alloys in metallurgy and for input inspection of metals in mechanical engineering. The big potential of the optical train of the microscope permits to use it in chemical industry for evaluating the structure of different materials.
The MK-3 microinspection station is fitted out with the highest-rate optics with enlarged observation field. To provide the realization of any customer's requests Planar offers a wide range of options to the microscope which are supplied on a separate order.
Using of a quintuple electromechanical nosepiece allows studying objects without a considerable loss of time for searching the object after having changed the magnification (after changing the objective the sharpness remains practically unchanged and the object under study remains in the center of the field of vision). According to the customer's wish, the objects can be investigated in bright and dark fields and in polarization and differential interference contrast modes. The MK-3 microinspection station allows carrying out the TV inspection and the computer image analysis. The station's design is highly ergonomic. It allows adjusting the eye base and carrying out the dioptric adjustment for operator's eyesight in a broad range. The magnification change is made by an electromechanical drive. An option is envisaged for fine and coarse displacement of the object stage and for easy and convenient switching between the modes. All this makes the work at the microscope free from fatigue even during several hours.
