The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object. ... If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.

The two main types of lenses found in light microscopes today are called the objective lens and the ocular (or eyepiece lens). The ocular lens, which is also called the eyepiece lens, is positioned at the top of the optical tube, while the objective lens is positioned at the bottom.

Best Answer: The difference is a simple microscope has one lens where a compound microscope has an objective lens and an eyepiece with a longer focal length. a simple microscope only has one type of lens, usually objective lens, but a compound microscope had both objective lens and ocular lens.

A simple microscope uses the optical power of single lens or group of lenses for magnification. A compound microscope uses a system of lenses (one set enlarging the image produced by another) to achieve much higher magnification of an object.

Cell Structure. ... A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
