Microscope Notes

Microscope Notes The microscope was developed in the 1600’s. Several people are given credit for the development of the microscope Zacharias Janssen: created the first microscope by putting two magnifying glasses together in a tube. Anton Von Leeuwenhoek, also credited with creating one of the first modern microscopes. Types of microscopes Simple: A simple microscope is a microscope with only two lenses total, and eyepiece and objective lens. Compound: These microscopes have three or more lenses that allow the observer to look at an object at different magnifications. Stereomicroscopes: These microscopes have and eyepiece lens for each eye. This allows the viewer to see the object in 3D; they are used to look at objects that are too thick to allow light through. Electron scanning microscopes: These are the most powerful microscopes; they can magnify objects over a million times. They use magnets to bend beams of electrons to magnify objects. Compound, simple, and stereomicroscopes use lenses to create the magnification. The type of lens they use is a convex lens. There are two basic types of lens: Convex which is thicker in the middle than on the edges, this lens magnifies and also will flip images. And concave, these lenses are thicker on the edges than in the middle.

To figure out the magnification you multiply the eyepiece, usually 10x by the objective printed on the side of the lens.
