A microscope is an optical instrument used to look at objects that cannot be seen by the naked human eye. From its invention, the microscope has had many uses that include tissue examinations and forensic examination. It is because of its many uses that the microscope is a permanent fixture in most kinds of labs whether medical or scientific. To understand the uses of the microscope, a person needs to know all the different parts of the microscope.

Types of a Microscope

There are numerous types of microscopes in the market that include. The oldest type of microscope, which is the optical microscope, uses light to generate and view specimen, and the electron microscope that uses electrons for specimen illumination. The following are parts of a microscope.

Parts of the Optical Microscope

One has to start from the basics to be able to understand the various parts of a microscope. Understanding the parts of the optical microscope and its microscope lab activities can help know how the other microscopes work.

  • Eyepiece Lens: It has a magnifying lens, which helps focuses the image from the specimen to the eye. The power of the magnifying glass could have the power of ten or fifteen. Higher magnification helps view smaller specimen.

  • Tube: This part of the microscope helps connect the top parts of the microscope, which are the objective lens and the eyepiece.

  • Adjust Knobs: These parts of the microscope include the coarse adjust and the fine adjust. The coarse adjust helps focus on specimen with low magnification. The fine adjust helps focus on specimen under either high or low magnification. This fine knob is placed lower than the coarse adjust.

  • Objective Lens: This can either have three or four lens. These lenses include the low power objective used to look at large specimen and also to get an overview of the specimen. The second most important objective lens is the high power objective part of the microscope, which gives you a much detailed view of any small specimen. The objective lenses are usually attached to the revolving turret or nosepiece.

  • Rack Stop: This helps adjust the closeness of the objective lenses to the specimen.

  • Glass Slide: The glass slide is another one of the important parts of a microscope since the glass slide helps hold the specimen. The glass slide is generally supported by the stage.

  • Condenser Lens: The condenser lens focuses the light onto the specimen.

  • Iris or Diaphragm: The iris or the diaphragm regulates and contrasts the amount of light on the specimen.

  • Light Source: Another part of the microscope is the light source that helps illuminate the specimen for proper viewing. The illuminator acts like the microscope mirror and reflects light from external sources.

  • Microscope Arm: The microscope arm supports the upper part of the microscope that includes the tube. The arm also helps connect the top part of the microscope to the base of the microscope.

  • Base: The base helps to support all the other parts of the microscope.

Microscopes are a big help in our fight against diseases as well as the development of science. This is why it is important to be familiar with the parts of a microscope.
