HPS 443 Zoom, trinocular

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.

The object can be illuminated from above as well as from below.

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.

Describes the position in which you look through the eyepiece, for example at 45° or straight.

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

Used to hold colour filters for contrast enhancement.
