condenser knob; adjusts the height of the condenser lens, which focuses light onto the specimen
G
Image: condenser knob; adjusts the height of the condenser lens, which focuses light onto the specimen
coarse focus knob; moves the stage up and down quickly to bring the specimen into near focus. it is never used in conjunction with lenses of 40x magnification & higher
H
Image: coarse focus knob; moves the stage up and down quickly to bring the specimen into near focus. it is never used in conjunction with lenses of 40x magnification & higher
fine focus knob; moves stage up and down very gradually to bring specimen into sharp focus. it's the only focus adjustment used with objective lenses of 40x magnification & higher

condenser (iris) diaphragm control; adjusts the diameter of the aperture through which light passes before entering the condenser lens. it regulates the amount of light captured by the condenser lensKpower switch; used to power the microscope on and off. the microscope should be turned off when not in use to preserve the life of the lampLlight source (lamp); provides illumination of the specimen being viewedMbrightness control; potentiometer that regulates the voltage applied to the lamp. the greater the voltage, the brighter the lampNbase; supports the microscope and houses the lamp & electronic components. it is also used when transporting the microscopeOthe circle of light visible through the microscope;
