Stereo microscope 33213, binocular

The upper element of a microscope. An eyepiece consists of several lenses and is used for visually observing the object. In microscopy, the magnification power is expressed as -x.

The light source illuminates the object and is available in various forms.

This refers to the magnification factor of a single microscope lens. A lens with the number 40 is referred to as a scale of 1:40 or simply a factor of 40 times. If you multiply the lens factor by the eyepiece factor, you get the magnification.

The object or specimen slide is positioned and centred on this.

A focusing wheel is used to focus the microscope on the particular object.
