What are the optical parts of a microscope?
The microscope optical train typically consists of an illuminator (including the light source and collector lens), a substage condenser, specimen, objective, eyepiece, and detector, which is either some form of camera or the observer’s eye (Table 1).
Which part of the microscope is responsible in enlarging the specimen?
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.
Which is part of the microscope magnifies the image?
