GENERAL HISTOLOGY

Detailed explanation-1: -Enlargement or magnification of a specimen is the function of a two-lens system; the ocular lens is found in the eyepiece, and the objective lens is situated in a revolving nose-piece. These lenses are separated by the body tube.

Detailed explanation-2: -They have an objective lens (which sits close to the object) and an eyepiece lens (which sits closer to your eye). Both of these contribute to the magnification of the object. The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.

Detailed explanation-3: -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.

Detailed explanation-4: -The eyepiece has several major functions: The eyepiece serves to further magnify the real image projected by the objective. In visual observation, the eyepiece produces a secondarily enlarged virtual image. In photomicrography, it produces a secondarily enlarged real image projected by the objective.

Detailed explanation-5: -The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. The lens closest to the eye is called the ocular, while the lens closest to the object is called the objective.
