Compound microscopes have dramatically transformed our understanding of microscopic life forms, revolutionizing both microbiology and medical science. Their invention paved the way for groundbreaking discoveries that continue to influence modern medicine and education.

Compound microscopes utilize two main types of lenses: objectives and eyepieces. Objective lenses come in various magnifications, typically ranging from 4x to 100x, while eyepieces usually have a fixed magnification, contributing to the overall magnification of the specimen being observed.

Focusing in a compound microscope is achieved primarily through coarse and fine adjustment knobs. Coarse adjustments provide quick changes in focus at lower magnifications, while fine adjustments allow for precise focus at higher magnifications, essential for observing intricate details of the specimen.

The compound microscope was first developed in 1590 by Dutch spectacle makers Zacharias Janssen and his father. Their design combined multiple lenses to achieve magnification, fundamentally changing the way organisms and objects were observed, which was start to a new invention.
