Old Bausch & Lomb research microscope catalogue.
I excavated this recently. It is dated 1937 and is fairly comprehensive, covering a lot of theory and eventually in the text, relating their hardware to it. There is a pretty good section on the accessories they offered too. I don't have a scanner but took some pictures of the 6 models they offered at the time. Objectives were achromats, fluorites or apochromats, with a few oddities such as glycerin immersion achromats and water immersion achromats appearing as well. Eyepieces were huygens,hyperplane, or compens with abbe, wide angle abbe, achromatic aplanatic and cardioid dark field condensers being offered. B & L didn't seem to consider the low positioning of the fine focus important yet but by the early 50's they did.
It's 19 pages and if anyone wants any information from it, just ask.

Re: Old Bausch & Lomb research microscope catalogue.
I bid on a DDE but lucked out. As I recall it sold for about $400-- a steal!

Re: Old Bausch & Lomb research microscope catalogue.
We may have been looking at the same one. There was one some time ago without objectives , which went even lower. I did not have any Bausch & Lomb apochromats at the time , so passed but even without trying I ended up with a bunch of B & L apochromats, eventually.
The DDE is a bit of a mystery to me. If the Spencer # 8 , to which it had to clearly bow, is ignored, the DDE's chief competitor for most of it's production years was the Spencer # 5, with which Spencer made a great effort to integrate ergonomics into the design. The fine focus is low and allows the arms to be in a relaxed position and only about an inch from the coaxial controls on the most commonly fitted R stage . On the DDE , the coarse and fine focus are suspended in mid -air beyond the head, about 10 inches from the stage controls, which are individual., not exactly designed for convenience.
I suppose if you adopted a lean on your elbows,hands in the air , tousled hair, shirt collar undone, sleeves rolled up and half smoked fag with an inch of ash hanging off it, sort of look...the haggard, wee hours of the morning, bourbon swilling, intrepid researcher only inches from curing syphilis for the G.I.s, kind of guy, then it probably works; at least in a movie , anyway.
The guy on the ergonomic Spencer # 5 would have a tweed jacket, bow tie, specs, a pipe and pat traces of LIpton from his broombrush moustache with a folded handkerchief..

Re: Old Bausch & Lomb research microscope catalogue.
It jumps out at me what a 'neck breaker' the GGBE stand would be due those vertical eyepieces...and yet the second model features this observation comfort design of angled binoc viewing. Beautiful equipment! charlie guevara ahhh for $20 one can purchase viewing comfort it notes at the bottom of the page.

Re: Old Bausch & Lomb research microscope catalogue.
Aside from the DDE, they are basically the same microscope stand, just with an alternate head choice, or stage and substage. Spencer had a more elaborate array of stands and had given up on vertical viewing bodies altogether by 1937. The B & L catalogue does mention whether the microscope needs to be tilted or not , since it is possible to angle the instrument conveniently, if your subject isn't likely to drain into your lap.charlie g wrote:It jumps out at me what a 'neck breaker' the GGBE stand would be due those vertical eyepieces...and yet the second model features this observation comfort design of angled binoc viewing.

Re: Old Bausch & Lomb research microscope catalogue.
The brochure page 8 comes right out and states:' for long viewing sessions the inclined binocular ..comfortable'. And the first page posted as the next page, offers inclined heads for $20 more than vertical head.
Such beautiful equipment. charlie guevara
