HISTORY OF MICROSCOPE ACCESSORIES

The first microscopes had no accessories. Initially, they were even limited to a single power of magnification. With progress in optics, came improvements in the instrument itself, and the need for accessories to make the most of what the microscope had to offer. These included Eyepieces of different powers, objectives of different powers and types, illuminating apparatus (both integrated into the microscope and separate), and apparatus to manipulate or restrain a subject. Accesories included apparatus used to prepare a specimen for view such as a microtome, or an apparatus to simply restrain a live specimen, as in a Livebox or Compressor. As more techniques were developed, accessories to allow their use were needed. These would include things like polarized light accessories or dark ground condensers.

MICROSCOPE ACCESSORIES ON THIS WEB SITE

This website features many accessories from microscopes of the 18th,19th and 20th centuries. Many accessories are discussed with their respective instruments, and are not shown here. The links to specific topics, e.g. compressors, give a good sampling of the respective accessories. I am grateful to be able to feature not only my own microscope accessories, but also those of other collectors kind enough to share them with us.

In addition to the accessories shown in the links, some are shown in the table below with links to dedicated pages. Not all accessories could be listed in the tables, so except for unusual single accessories, you will find a greater selection on the pages dedicated to the accessory in question.

If you have a question about one of your accessories please feel free to contact me and I will try to answer you. This web page is being updated as often as feasible but is not yet complete.



An article I have written details and how to identify many of the known accessories associated with antique microscopes is now available on this website.

For a detailed discussion of many accessories see the accessory section of the web pages about the Grand Van Heurck Microscope in this collection.

For a detailed discussion of another large collection of accessories for an older microscope, see the accessory section of the early 1860's Smith & Beck Best microscope on this website.

The Compressor Article is a dedicated page about the different types of compressoria.

The Article about Liveboxes documents the history and different types of these 'animalcule' cages.

An article about frog plates and fish pans is now on this site.

The article onCamera Lucidas for the Microscope follows the history of these drawing aids as applies to the microscope.
