Eyepiece Lens: the lens at the top that you look through. They are usually 10X or 15X power.
Tube: Connects the eyepiece to the objective lenses
Arm: Supports the tube and connects it to the base
Base: The bottom of the microscope, used for support
Illuminator: A steady light source (110 volts) 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. Stage clips hold the slides in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs. One moves it left and right, the other moves it up and down.
Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X. To have good resolution at 1000X, you will need a relatively sophisticated microscope with an Abbe condenser. The shortest lens is the lowest power, the longest one is the lens with the greatest power. Lenses are color coded and if built to DIN standards are interchangeable between microscopes. The high power objective lenses are retractable (i.e. 40XR). This means that if they hit a slide, the end of the lens will push in (spring loaded) thereby protecting the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses.
Rack Stop: This is an adjustment that determines how close the objective lens can get to the slide. It is set at the factory and keeps students from cranking the high power objective lens down into the slide and breaking things. You would only need to adjust this if you were using very thin slides and you weren't able to focus on the specimen at high power. (Tip: If you are using thin slides and can't focus, rather than adjust the rack stop, place a clear glass slide under the original slide to raise it a bit higher)
Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400X and above). Microscopes with in stage condenser lenses render a sharper image than those with no lens (at 400X). If your microscope has a maximum power of 400X, you will get the maximum benefit by using a condenser lenses rated at 0.65 NA or greater. 0.65 NA condenser lenses may be mounted in the stage and work quite well. A big advantage to a stage mounted lens is that there is one less focusing item to deal with. If you go to 1000X then you should have a focusable condenser lens with an N.A. of 1.25 or greater. Most 1000X microscopes use 1.25 Abbe condenser lens systems. The Abbe condenser lens can be moved up and down. It is set very close to the slide at 1000X and moved further away at the lower powers.
Diaphragm or Iris: Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. There is no set rule regarding which setting to use for a particular power. Rather, the setting is a function of the transparency of the specimen, the degree of contrast you desire and the particular objective lens in use
The main parts of a microscope include the eyepiece (where you look into), the objective lenses (magnify the specimen), stage (holds the specimen), condenser (focuses light onto the specimen), and the light source (illuminates the specimen). These components work together to magnify and focus light on the specimen for viewing.

What are the names of some of the parts of a microscope?
Some parts of a microscope include the eyepiece, objective lens, stage, arm, and base. These components work together to magnify and view specimens accurately.
What parts supports the whole body of microscope?
The base of the microscope supports the entire instrument and provides stability. Additionally, the arm holds the upper parts of the microscope, such as the stage and eyepiece, in place. Both the base and arm work together to support the entire body of the microscope.
What type of microscope would you use to see the parts of a cell?
You would use a light microscope to see the parts of a cell. This type of microscope uses light to magnify the structures within a cell, allowing you to visualize organelles such as the nucleus, mitochondria, and cell membrane.
What common parts are found in both compound microscope and stereo microscope?
Both compound microscope and stereo microscope typically include a base, an arm, an objective lens, an eyepiece, a stage, and a focusing knob. These common parts contribute to the basic structure and functionality of both types of microscopes.
What is the classification of the parts of the microscope?
The parts of a microscope can be classified into two main categories: optical components, which include the eyepiece, objective lenses, and stage, and mechanical components, which include the frame, focusing system, and illumination system. The optical components are responsible for magnifying and focusing the specimen, while the mechanical components support and adjust the position of these optical parts.
What are the three main parts of a compound microscope?
The compound microscope has three main parts, The three main parts of a microscope includes the illuminating parts, the magnifying parts, and the mechanical parts.
Where can one order parts for a microscope?
Microscope parts can be purchased online at sites such as Microscope World, Amazon, and eBay. One can also find a wide selection of microscope parts online at The Microscope Depot.
