Two functions of microscope
Magnify and resolve details of your specimen
How do microscopes magnify objects
they have a two lens system that is capable of reflecting and refracting light which magnifies these objects
Father of Microscopy
Antoine Van Leeuwenhoek
Types of Microscopes
Simple Microscope
Compound Microscope
Light Microscope
Electron Microscope
Microscope that only utilizes one lens to magnify objects
Simple Microscope
Microscope that has a two lens system
Compound microscope
What are the lenses of a compound microscope
Objective lens and eye piece
A microscope that uses light as a source of illumination
Light Microscope
Magnifies objects by the utilization of beams of electrons
Electron Microscope
Types of electron microscopes
Scanner Electron microscope
Transmission electron microscope
Scans the surface of an object then magnifies it
Scanner Electron Microscope
Allows beams of electrons to pass through the object itself to provide a clear picture in somewhat 3D model

Ethnobotany
How are images of the object presented in a compound microscope
Inverted
Lenses that stay focus when magnification/focal length is changed
Parfocal lenses
what happens to an image when you open the iris diaphragm
Opening the iris diaphragm would make the images brighter and more apparent
Should you close one eye in viewing the microscope?
If the microscope is a biocular compound microscope, then both eyes must be opened.
