The working principle of the compound microscope is based on optical magnification technology, and the observation of tiny objects is mainly achieved through the combination of objective lens and eyepiece. The structure of the compound microscope includes objective lens, eyepiece, tube, stage, focusing knob, lighting system and condenser, each of which has its specific function:
Objective lens: responsible for the initial magnification of the details of the object. Objective lenses of different magnifications can be switched to obtain different magnification levels.
Eyepiece: magnify the image formed by the objective lens again so that the observer can see the details more clearly.
Barrel: connects the objective lens and the eyepiece to keep the light path stable.
Stage: used to place the sample to be observed.
Focus knob: accurately adjust the focal length to make the image clear.
Lighting system: provides sufficient and uniform light, and the condenser focuses the light on the sample to enhance the brightness.
