Latest Issue: August This year got off to a great start for our collections when we took a call about a microscope that might be a Manhattan Project-era artifact but was on its way to Lab salvage. After it was determined there was no radiation associated with the item itself, it was brought to the Museum and a condition report created. It turned out to be a Spencer Lens Company polarizing microscope, complete with a graduated, rotatable stage.
Its manufacture date was , just outside of Manhattan Project history. It came with its original wooden case, lockable, with the key attached on a length of ribbon. It’s unusual that the key hadn’t been lost in the ensuing 60 or more years! A monocular eyepiece is attached, but it also has a binocular piece, for use with both eyes, that is nestled in a velvet-lined accessory drawer.
Also present are over half a dozen other lenses, a polarizing light filter, and a Wray copying lens. Such is the world of artifacts….

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.

In this section are grouped some of the most significant stereo microscopes dating from the beginning of the twentieth century to about One could think these old models as average quality with respect to modern ones.

The stand has a very good extension power both by rack and by an additional sliding component, making possible to observe voluminous objects such as rocks and minerals, plants and so on. It can be upgraded by the addition of eyepieces of different power, and by a transmitted light base. Made in Japan by Unitron in the ’70ies it was very good for the price. This one has a magnification power of 20x and 40x , and with the 15x eyepieces of 30x and 60x. Classic features of the ’50ies, where the grey dominated not only for microscopes, but also for cars and many other objects built in that period.

Thanks, Radazz. Re: Spencer model? The 30 and 40 had been already made for quite a while by That might have been the last year they made them. Spencer used to continue older designs in production for quite a few years, I guess until the older and more conservative users stopped buying them.
