Invention Of The Microscope
~1600 the microscope is invented by Robert Hooke. -
Period: to
History Of Microscopy
-
Hooke Publishes 'Microghia'
His book about the findings he's made with the aid of the microscope. Cells and bacteria are among his discoveries. -
Achromatic Lenses for Spectacles
These new lenses preceded the invention of Achromatic lenses for the microscope, which would bring new power to scientists everywhere, -
Achromatic Lens Brings New Power
New achromatic lenses introduce new resolution and power to the microscope world, allowing better discoveries to be made. -
Cell Theory Formally Propsed
While humans have aknowleged cells for a century, the formal cell theory has finally been proposed by Theodor Schwann and Matthias Schleiden. This theory finally adresses that cells are the basic unit of life. -
Ernst Abbe's "Abbe Sine Condition" Published
Ernst Abbe's work on the microscope clearly outlines how to position lenses for the optimal resolution and zooming power, as before this all setups had been trial and error. -
Mitosis is Discovered by Walther Flemming
Mitosis is finally found in cells when they split to form two new cells which continue to split into two, as they reproduce to form more. This is a vital discovery contributing to cell theory. -
Book on Heredity Published
August Weismann publishes a book on heredity, and greatly influences biologists all around the world. The development of the microscope has helped to make these breakthroughs. -
Powell and Lealand Make High Power Objectives
Powell and Lealand company manufactures high-powered objective lenses for new microscopes. -
Book on Mutations Published
De Vries publishes a new book on mutations and how different cells and DNA can change a creature's attributes and traits. Bringing more knowlege of cells aids this movement. -
The First Commercial UV Microscope
The fist commercial UV microscope is invented by the Zeiss company and has twice the resolution of a visible light microscope. -
Fritz Zernike Uses Phased Angle of Rays to View Cells
Fritz Zernike is the first to discover that you can view unstained cells by using the phased angle of rays. Unstained cells are more difficult to see considering they aren't colored. -
First Electron Microscope
Max Knoll and Ernst Ruska create the very first electron microscope which uses electrons instead of light to 'see' making it more powerful. -
'Contrast Microscope' Is Coined
Zernike coins the phrase, 'contrast microscope,' referring to a technique where changes in brightness allow us to see things we couldn't before. -
First Commercial Electron Microscope
Siemens company provides the first commercially-available electron microscopes, allowing more discoveries to be made since they're in the hands of more scientists. -
First ultra-microtome built by Porter and Blum
This technology built for the electron microscope can slice cells into section for extreme zoom levels. -
Field Ion Microscope Is Invented
This microscope made by Erwin Wilhelm Müller is the first microscope that can see atoms, and helps people everywhere to further understand the forms of matter. -
Scanning Probe Microscope Invented
This new microscope works by measuring the length of currents. -
Atomic Force Microscope
This new micrscope measures the force of an object rather than current lenghts. -
Compound Optical Microscope
A compound optical microscope is different to the optical microscope because it uses different eye pieces to create different volumes of magnification.
