The body tube of a microscope supports the objective lens system and the eyepiece. This tube holds the optics in place and allows for adjustments to focus on the specimen.
Objective lenses are found on the nose piece of a microscope and they range from low to high magnification. The user can rotate the nose piece to switch between different objective lenses to achieve different levels of magnification when observing a specimen.
The draw tube and the body tube connect the eyepiece to the revolving nose-piece.
The part of the microscope that you look into is called the eyepiece.
The iris diaphragm in a compound microscope controls the amount of light that passes through the specimen being observed. By adjusting the aperture, it enhances contrast and resolution by optimizing illumination for different magnifications and specimen types. This feature allows for clearer images and helps in revealing finer details of the sample.
The arm or the frame of the compound microscope supports the body tube.
the arm
The base of a microscope supports the weight of the entire microscope. It provides stability and balance to prevent the microscope from tipping over during use.
