1.Microscope Types and Parts

Microscope Types and Parts

Microscopes were invented by Antonie van Leeuwenhoek
There are two types of microscopes: 

1. A light microscope, or a compound microscope, uses light rays and magnification lens's to look at small objects

2.An electron microscope uses beams of electrons to magnify an image and make it viewable 

Light(compound) Microscope:

-Contains more than one lens, the lenses are the objective lens, and the ocular lens

-More commonly used today due to price

-Contains it's own light source

-Earliest and simplest form of microscope

-Hans and Zacharias Janssen invented this microscope in the 1590's, then, Anton von Leeuwenhoek and Robert Hooke made advancements in the 17th century 

Electron Microscope:

-Electron microscopes have a higher magnification and resolution than light microscopes

-The electron microscope uses electrostatic and electromagnetic lenses

-Electron microscopes are an important tool in laboratories 

-Researchers use it to examine biological materials, a variety of large molecules, medical biopsy samples, and the characteristics of various surfaces.

-The first electron microscope prototype was built in 1931 by German engineers Ernst Ruska and Max Knoll, Two years later, Ernst constructed the first actual electron microscope

Reflection:
I was surprised that electron microscopes were so big. I learned a lot about electron microscopes, and all the uses for it. Microscopes are mainly used in science and biology, but you can use microscopes to look at almost anything. I already knew about the light/compound microscope because it's the most common type and is commonly found in classrooms. I liked this objective because we got to actually use the light microscopes to look at cells.
