Microscopy is the science of investigating small objects and structures using such an instrument. Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the way the instruments interact with a sample to create images, either by sending a beam of light or electrons to a sample in its optical path, or by scanning across, and a short distance from the surface of a sample using a probe.

The most common microscope and the first to be invented is the optical microscope , which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope , the electron microscope both the transmission electron microscope and the scanning electron microscope and the various types of scanning probe microscopes.

Although objects resembling lenses date back 4, years and there are Greek accounts of the optical properties of water-filled spheres 5th century BC followed by many centuries of writings on optics, the earliest known use of simple microscopes magnifying glasses dates back to the widespread use of lenses in eyeglasses in the 13th century. The first detailed account of the microscopic anatomy of organic tissue based on the use of a microscope did not appear until , in Giambattista Odierna’s L’occhio della mosca , or The Fly’s Eye.

The microscope was still largely a novelty until the s and s when naturalists in Italy, the Netherlands and England began using them to study biology. Italian scientist Marcello Malpighi , called the father of histology by some historians of biology, began his analysis of biological structures with the lungs. The publication in of Robert Hooke ‘s Micrographia had a huge impact, largely because of its impressive illustrations.

A significant contribution came from Antonie van Leeuwenhoek who achieved up to times magnification using a simple single lens microscope. He sandwiched a very small glass ball lens between the holes in two metal plates riveted together, and with an adjustable-by-screws needle attached to mount the specimen. On 9 October , van Leeuwenhoek reported the discovery of micro-organisms.

Nothing ages as elegantly as an antique microscope. A bridge to an age when craftsmanship was as important as functionality, a vintage microscope is a work of art as well as science. In the late 16th century several Dutch lens makers designed devices that magnified objects, but in Galileo Galilei perfected the first device known as a microscope. His invention, a compound microscope, had a convex and a concave lens. Later that century, Anton van Leeuwenhoek refined the microscope for biological research.

These first fledgling microscopes were generally built and used by a scientist. They can only be found in museums and are not available to the average antique microscope collector. Usually made of brass, the first microscopes were monocular instruments with simple lenses. For further history reading feel free to follow our link on the History of the Microscope. The German lens maker, Carl Zeiss, excelled at crafting precision lenses and began manufacturing microscopes in Initially building single lens instruments, in his firm began designing compound microscopes.

Made of brass, many of these instruments had a black japanned base.

Because these instruments all date from the ‘s and ‘s or before, information on them is becoming harder and harder to find. Again, though, for AO Microscopes, what cleaning agent to use shouldn’t be a mystery because recommendations are given by AO in the manuals for your specific scope as found below. Note: Many of these files were furnished to me by Robert Tolley, after I had contributed a Darkfield manual and the newer Series 10 manual, who in-turn, received it from others, so I believe that many amateurs have probably contributed to this collection over the years.

I have since tried to add to it as documents or scans have been kindly sent to me, or I have been able to bid on them on eBay. I am searching for an AO Series 2 or Series 4 reference manual, if you have one, please contact me. Also this pdf version contributed by Carl Hunsinger.
