Understanding Microscope Parts and Their Functions in Magnification

This chapter delves into the essential parts of a microscope, including the base, stage, ocular, and adjustment knobs. We explore the various objective lenses—scanning, low-power, high-power, and oil immersion—and their respective magnifications. The total magnification (TM) is calculated by multiplying the power of the ocular lens (typically 10x) by the objective lens power. Additionally, we discuss the concept of parfocal microscopes, designed for easy focusing when switching between lenses.
