- Is the part of the microscope that houses the primary lenses of the microscope. Hence, it is located just above the objectives. The lenses are mounted on a revolving turret, so that one can conveniently select a specific objective lens, as per the requirements.
- Is the metal part that mechanically supports both the objectives and eyepiece. It should be aligned in such a manner that the objective and eyepiece lens are in one plane. Also, the length of the body tube is fixed, either 170 millimeter or 180 millimeter.
- These are the primary optical components of a microscope. As the name suggests that its lenses are placed near the object. A typical compound microscope is constructed with 3 or 4___ lenses, having different magnifying powers, ranging from 4X-100X.
- It is the curved part that connects the base of the compound microscope with the top portion. Its purpose is to support the body tube. For safe handling and picking up of the microscope, one hand supports the arm and the other supports the base.
- It increases the clarity of the image to a certain extent, particularly while viewing the specimen with more than 400X magnification. Based on the model, a compound microscope may or may not suppor it.
- This is the flat portion, where the specimen to be observed is placed on a slide. If the model supports, one can use a mechanical stage for fine movements of the slide.
- Installed just underneath the stage in a compound microscope. It is an adjustable, rotating disk with different sized holes.
- Is the lens with which we view the specimen in a compound microscope. The power of the eyepiece lens is usually 10X or 15X.
- KImmy wants to make sure that the glass slide will be in place while shes using the microscope. What should she operate?
- Chris wants to control the light that enters through the microscope. What part should he manipulate?
