A condenser serves to ensure a uniform homogeneous illumination of the object. The Abbe condenser consists of a lens system and an adjustable diaphragm. With it, you can set the optimal contrast for the object.


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.

Image scale

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.

Lens type

Describes the optical design of the lens.

Light source (1)

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


Specifies how much larger an object appears compared to when viewed with the naked eye.
