AO (American Optical) Spencer Microscope Manuals and Catalogs
Ok, what is going on here . . .?
I'm a microscope enthusiast and amateur microscopist, if you will, and the microscopes that I own (OK, that I could afford :-) although it would be hard to buy something really better -- they are excellent!) are AO (American Optical ) or AO Spencer microscopes. Because these instruments all date from the 1950's and 1960's or before, information on them is becoming harder and harder to find . . . so here you go!

|Advice on Microscopy and Using Your Microscope?|
|You should read Micscape every month for fascinating articles on the world of amateur microscopy.||The encyclopedia of all microscope knowledge on the web is Molecular Expressions -- spend some time there if you can.|
|Many knowledgeable microscope enthusiasts frequent Group.io's 'Microscope' forum. If you need to locate a manual for particular microscope, or just need help with pretty much any microscope related issue, join the forum (it's free!), leave a message, and they often can help or direct you to a source of help.||Also visit and query the Amateur Microscopy net which also is frequented by knowledgeable enthusiasts and, as a bonus, contains arguably the best photomicrography found anywhere in the world (professional or amateur!).|
|Robert Bagnell's 'Light Microscopy', a text for his Pathology 164 course at the UNC School of Medicine, is a very excellent, complete, on-line book on microscopy.||Zeiss's 'Microscopy from the very beginning' is another excellent introduction to modern microscopy (note: download the pdf brochure).|
for advice on cleaning your microscope's optics?
First, see the excellent page here.
Remember though that the cement used in microscope optics changed greatly
over the years and you should definitely consult the manufacturer's
directions in the manual for your specific microscope. The Zeiss document, 'The Clean Microscope', can be found
(download the brochure)).
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.
|Viewing an excellent online video: Imaging the Hidden World: the Light Microscope (1984) by Bruce Russell will give you a good idea of what to expect from microscopy as a hobby. View it! You'll enjoy it I promise.|
"What about books?" someone might ask.
A. For microscopy as a hobby in general, you can't do much better than Werner Nachtigall's 'Exploring with the Microscope'. This book is out of print but there are almost always used, as new, copies for sale either on eBay or from bookfinder.com for less than $30. It really is a 'must have'.
B. For learning about the microscope and how to use it, and what to buy, etc., in my opinion you can't do better than Dave Jackson's 'Better Microscopy -- Vols 1 & 2 Special Combined Edition' for $22 from lulu.com. Get it! No hobbyist (and maybe a professional or two too ;-) ) should be without this book .
C. For the history of the microscope, and lots of insights into why things evolved as they have, Hartley's 'The Light Microscope: It's Use and Development' is the ultimate resource. Unfortunately, it is usually very expensive, but watch on bookfinder.com . . . sometimes you can find one for less than $50.
D. Don't miss Robert Bagnells 'Light Microsopy' . . an online book that is very excellent and quite advanced.
E. For a very detailed, and expert, look at instruments in use in the 1950s, and early '60s -- an era in which many hobbyists' scopes were manufactured -- George Needham's 'The Practical Use of the Microscope' reigns supreme. Look for it on bookfinder.com. Used copies can often be had for less than $50.
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

11. The Effective Use and Proper Care of the Microscope note: A must read!
This book was revised and republished over the years as AO Spencer's microscope line evolved. There are:
|The 1941 edition (7.44 MB)||Eldred Spell has kindly contributed this edition which features the earlier black scopes such as the Model 33.|
|The 1949 & 1954 edition (5.30 MB):||These editions are identical (i.e. the 1954 edition was simply re-published from the 1949 edition) and feature the newer black scopes such as the Series 35, Scholar's Microscope, etc.|
|The 1956 edition & 1958 edition (5.40 MB)||These editions are identical (thanks to Jason Raitano for sharing scans of his 1956 edition to compare with my 1958 example). Features the MicroStar Series 2 & 4 'gray' scopes and associated accessories and models.|
|The 1959 & 1960 editions||Rumored versions . . . I have not seen them to confirm.|
Why am I trying to get a copy of multiple versions? Unreasoned obsession? No . . . well maybe :-) . . . the reason one might want a specific year is that it contains instructions for a certain range of microscope models. I believe that during the years above, these are the only 'users manuals' AO Spencer provided for their microscopes.
