Short Description

Focusing holders hold the microscope body and contain the mechanism that raises or lowers the body to focus on the specimen. Complete stands include their own focusing holders. But for other kinds of tasks, however, it may be necessary to mount the microscope body on a boom arm stand or directly onto a machine or some other surface.

Focus Holders


Focusing holders hold the microscope body and contain the mechanism that raises or lowers the body to focus on the specimen. Complete stands include their own focusing holders. But for other kinds of tasks, however, it may be necessary to mount the microscope body on a boom arm stand or directly onto a machine or some other surface. The focusing holders below offer a range of options for such applications.
