1．Use：

Trinocular inverted optical microscope 4XC-V can be used to observe the surface of the organizational structure and form of operation to observe the surface of the sample downward, parallel with the work surface, so the height and shape of the sample has nothing to do for the larger sample and more convenient operation.    The instrument has the largest mobile stations and a variety of contents of the slide aperture, suitable for the operation of a larger sample; and it reflect coaxial external lighting system and easy to adjust optical path, insert the filter and more change light bulbs. With lift limit device with a focusing system, the specimen with the objective to avoid the bump, and the quantities do not have to repeat testing focus.

Metallographic Microscope System configuration in addition to high-definition image sensor cameras, and image processing systems, such as operating microscopes focusing simultaneously displayed in the display by the image processing system for real-time image processing, editing, storage and output (such as printing photos) or access to multimedia systems and e-mail.
