Substage condenser knob

Abbe condenser function

concentrates and controls the light that passes through the specimen and enters the objective

Alternative body tube function

separates the objective and the eyepiece and assures continuous alignment of the optics

Aperture function

hole in the microscope stage where light from the source passes through to reach the stage

Arm function

joins the base to the head and the eyepiece tube to the base ; also used for carrying the instrument

Base function

supports the entire microscope structure

Coarse adjustment knob function

moves the stage up and down rapidly for focusing

Diopter setting adjustment ring function

corrects any difference in vision and compensates for the differences in vision between the viewer’s two eyes

Draw tube function

carries the ocular ; controls tube length and so effect corrections for the objective lens

Dust shield function

prevents dust from settling on the objectives

Fine adjustment knob

moves the stage up and down slowly for focusing

Interpupillary adjustment wheel function

adjusts the width between the eyepieces to the width of the observer's eyes for clearer observation

Iris diaphragm function

controls the amount of light that reaches the specimen

Iris diaphragm lever function

adjusts the diaphragm’s positioning

Mechanical stage function

where specimen is placed ; holds microscope slide in place

Mechanical stage controller function

moves the position of the stage

Mirror function

reflects light to the specimen through the bottom of the stage allowing for clearer viewing

Mirror rack function

holds the mirror

Ocular/Eyepiece function

used to look at the specimen through a magnified view ; is the lens closest to viewer’s eyes

Objectives’ function

magnifies the view of the specimen ; is the lens closest to the specimen

Pillar function

vertical part on the base that provides structural support to the rest of the microscope

Revolving nosepiece function

used for switching between objective lenses and magnification

Stage clip

holds the slides in place

Substage condenser function

focuses light onto the specimen

Substage condenser knob function

moves the condenser up and down
