Despite these great achievements in microscopy, microscopes didn't change much over the next 200 years, even though there were imperfections when viewing an object due to the different refraction of light.
In the 1850s, German engineer Carl Zeiss began making refinements to the lenses he used in the microscopes he manufactured.
There is a lens called "the objective" which produces a primary magnified image.
Then there is another lens called "the eyepiece" or "ocular," which magnifies that first image.
In a long and fruitful collaboration, Abbe carried out theoretical studies of optical principles, improving the understanding of the optical quality of a microscope.
With the advancement of technology and improved optics, the microscope as we know it today came into being.
The earliest simple forms of magnification were magnifying glasses, usually about 6x - 10x and were used for inspecting tiny insects such as fleas, hence these early magnifiers called "flea glasses".
Newlywed husbands and wives would take turns answering (often risque) questions while their spouses ...In actual practice, there are several lenses used for both the objective and ocular, but the principle is that of two-stage magnification.It is believed that Zacharias Jansen's father, Hans, helped him build the first microscope in 1595.The microscope was said to have a magnification of 3x when fully closed, and 9x when fully extended.Although ordinary magnifying glasses are basically a simple microscope, when we speak of the invention of the microscope, we really mean the "compound microscope".
