The compound microscope contains a lens system, illumination system, and a body
consisting of a base, body tube, and nosepiece. This instrument is used to magnify minute objects to
such a degree that the details of their structure can be analyzed.
Parts
Oculars/Eyepiece- The lens the Arm - connects the body tube to the
