Its found under the stage of the microscope and its primary role is to control the amount of light that reaches the specimen. Diaphragm – it’s also known as the iris.More sophisticated microscopes come with an Abbe condenser that has a high magnification of about 1000X. The higher the magnification of the condenser, the more the image clarity. They play a major role in ensuring clear sharp images are produced with a high magnification of 400X and above. They are found under the stage next to the diaphragm of the microscope. Condenser – These are lenses that are used to collect and focus light from the illuminator into the specimen.It captures light from an external source of a low voltage of about 100v. Microscopic illuminator – This is the microscopes light source, located at the base.Aperture – This is a hole on the microscope stage, through which the transmitted light from the source reaches the stage.The most common stage is the mechanical stage, which allows the control of the slides by moving the slides using the mechanical knobs on the stage instead of moving them manually. They have stage clips that hold the specimen slides in place. Stage – This is the section in which the specimen is placed for viewing.There are two types of adjustment knobs i.e fine adjustment knobs and coarse adjustment knobs. The Adjustment knobs – These are knobs that are used to focus the microscope.
It is movable hence it cal revolve the objective lenses depending on the magnification power of the lens. Nose piece – also known as the revolving turret.Each lens has its own magnification power. There are about 1- 4 objective lenses placed on one microscope, in that some are rare facing and others face forward. They have a magnification power of 40x-100X. Objective lenses – These are the major lenses used for specimen visualization.For monocular microscopes, they are none flexible. In some microscopes such as the binoculars, the eyepiece tube is flexible and can be rotated for maximum visualization, for variance in distance. It carries the eyepiece just above the objective lens. Eyepiece tube – it’s the eyepiece holder.Its standard magnification is 10x with an optional eyepiece having magnifications from 5X to 30X. This is the part used to look through the microscope. The optical parts of the microscope are used to view, magnify, and produce an image from a specimen placed on a slide. Optical parts of a microscope and their functions This description defines the parts of a microscope and the functions they perform to enable the visualization of specimens. Microscopes are generally made up of structural parts for holding and supporting the microscope and its components and the optical parts which are used for magnification and viewing of the specimen images. They can view very small specimens and distinguish their structural differences, for example, the view of animal and plant cells, viewing microscopic bacterial cells. Their ability to function is because they have been constructed with special components that enable them to achieve high magnification levels. Depending on the type of lens, it will magnify the specimen according to its focal strength. Microscopes are made up of lenses for magnification, each with its own magnification powers. Microscopes are instruments that are used in science laboratories to visualize very minute objects such as cells, and microorganisms, giving a contrasting image that is magnified.
