What are the mechanical parts of a compound microscope?
What are the mechanical parts of a compound microscope?
(A) Mechanical Parts of a Compound Microscope. 1. Foot or base. It is a U-shaped structure and supports the compound microscope. 2. Pillar. It is a vertical projection. This stand rests on the base and supports the stage.
What is the function of the knobs on a microscope?
Knobs (fine and coarse) By adjusting the knob, you can adjust the focus of the microscope. The majority of the microscope models today have the knobs mounted on the same part of the device. Image 5: The circled parts of the microscope are the fine and coarse adjustment knobs.
What is a rack stop in microscopy?
The rack stop controls how far the stages should go, preventing the objective lens from getting too close to the specimen slide, which may damage the specimen. It is responsible for preventing the specimen slide from coming too far up and hit the objective lens. Two parameters are fundamental in microscopy: magnification and resolution.
What do the numbers on the eyepieces of a microscope mean?
At the top of the body tube, a lens is planted which is known as the eyepiece. On the rim of the eyepiece, there are certain markings such as 5X, 10X, 15X, etc. These indicate the magnification power.
What is a diopter adjustment on a microscope?
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. Arm: The arm connects the body tube to the base of the microscope.
What is the body tube on a microscope used for?
Body tube. The upper part of the arm of the microscope comprises a hollow and tubular structure known as the body tube. The body tube can be shifted down and up using the adjustment knobs. 10. Fine adjustment knob. It is the smaller knob, which is used for sharp and fine focusing of the object.
What is a condenser focus knob on a microscope?
Condenser focus knob – this is a knob that moves the condenser up or down thus controlling the focus of light on the specimen. Abbe Condenser – this is a condenser specially designed on high-quality microscopes, which makes the condenser to be movable and allows very high magnification of above 400X.
