Before exploring the parts of a compound microscope , you should probably understand that the compound light microscope is more complicated than just a microscope with more than one lens. First, the purpose of a microscope is to magnify a small object or to magnify the fine details of a larger object in order to examine minute specimens that cannot be seen by the naked eye. Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens.

Parts of the compound microscope Fig. These include base or foot, pillar, arm, inclination joint, stage, clips, diaphragm, body tube, nose piece, coarse adjustment knob and fine adjustment knob. It is the basal, horse shoe-shaped structure. It provides support to all the remaining parts of the microscope. A joint at which the arm is attached to the pillar of the microscope is called inclination joint. It is used for tilting the microscope. It is a flat rectangular plate attached to the lower end of the arm.

Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.

Though modern microscopes can be high-tech, microscopes have existed for centuries — this brass optical microscope dates to , and was made in Munich, Germany. A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell , its nucleus, mitochondria , and other organelles. While the modern microscope has many parts, the most important pieces are its lenses. A simple light microscope manipulates how light enters the eye using a convex lens , where both sides of the lens are curved outwards. When light reflects off of an object being viewed under the microscope and passes through the lens, it bends towards the eye.


The compound microscope has two systems of lenses for greater magnification, 1​) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the​.

The optical microscope , also referred to as a light microscope , is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although many complex designs aim to improve resolution and sample contrast.

Microscopy Exercises. The typical compound light microscope Fig. Electron microscopes extend this range further allowing us to see objects as small as 0. Needless to say, development and use of microscopes has vastly improved our understanding of cells and their structure and function. Figure 1.
