Microscopes with mechanical stage

Drug carrier

— presence of a preparation agent in the design of the object table.

The preparation guide is a device for smooth movement of slides under the microscope lens, as well as fixing the conditional coordinates of individual sections of the preparation. Mechanisms are responsible for the movement, allowing the glass to be shifted separately in the longitudinal and transverse directions. Coordinate fixation is provided by special scales with verniers, the accuracy of determining coordinates can be from 0.1 to 0.01 mm.

This feature is found exclusively in biological microscopes (see "Type"). Its presence can be extremely important for studies involving high magnifications. Without a slider, the glass would have to be moved by hand, and finding certain areas would be a very difficult, if not impossible, task.
