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.

Working Principle and Parts of a Compound Microscope (with Diagrams)

Read this article to learn about the working principle and parts of a compound microscope with diagrams! The most commonly used microscope for general purposes is the standard compound microscope. It magnifies the size of the object by a complex system of lens arrangement. It has a series of two lenses; i the objective lens close to the object to be observed and ii the ocular lens or eyepiece, through which the image is viewed by eye. Light from a light source mirror or electric lamp passes through a thin transparent object Figure 4. As light passes directly from the source to the eye through the two lenses, the field of vision is brightly illuminated. That is why; it is a bright-field microscope.

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. 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. Body tube Head : The body tube connects the eyepiece to the objective lenses.

Microscope Parts & Specifications

Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope vs. The simplest optical microscope is the magnifying glass and is good to about ten times 10X magnification. Basic parts of the microscope:. They are usually 10X or 15X power. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage. Stage clips hold the slides in place.

Eyepiece Lens: the lens at the top of the microscope that you look through. They eyepiece is usually 10x or 15x power. Illuminator: A steady light source v used in place of a mirror. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage. Stage: The flat platform where you place your slides.

Microscopes

This is the first lens that helps to magnify the image. The smallest distance that can be distinguished between two points is called resolution. This part is the one on top where users view or look through the device; the eyepiece tube is the tube that connects the ocular lens to the device itself.

A compound microscope is a microscope that uses multiple lenses to enlarge the image of a sample. Typically, a compound microscope is used for viewing samples at high magnification 40 - x , which is achieved by the combined effect of two sets of lenses: the ocular lens in the eyepiece and the objective lenses close to the sample. Light is passed through the sample called transmitted light illumination.
