Answer:

EYEPIECE(The eyepiece, or ocular, magnifies the primary image produced by the objective; the eye can then use the full resolution capability of the objective. The microscope produces a virtual image of the specimen at the point of most distinct vision, generally 250 mm (10 in.) from the eye.)

SCANNING POWER(A scanning objective lens provides the lowest magnification power of all objective lenses. 4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.)

OBJECTIVE LENS(Objective Lenses - The objective lens gathers light from the specimen, magnifies the image of the specimen, and projects the magnified image into the body tube.)

BASE(The bottom of the microscope, used for support Illuminator: A steady light source (110 volts) used in place of a mirror.)

COARSE(A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.)

ADJUSTMENT(The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus. The gearing mechanism of the adjustment produces a large vertical movement of the stage with only a partial revolution of the knob.)
