No problem ... I'm sure we can get there if people measure their various 'scopes.
I can check my Nachet stereo-zoom tonight.

Some numerical indication of what you consider to be a 'fantastically wide' and/or 'disappointingly narrow' field of view would be helpful. I find it convenient to print a few concentric circles of known diameter, for estimating the view at various magnifications. ... I will try attaching a PDF of m...

Stan, Here's a good description of how to make a blood-smear slide: https://www.uvm.edu/~jschall/pdfs/techniques/bloodsmears.pdf The supporting photos can be seen here: https://www.uvm.edu/~jschall/techniques.html I think you will find this technique gives you the view that you want. Best Wishes Mic...

What a splendid beast !!

Regarding the problem with file size: May I suggest that you post a few 'crops' from the full-resolution image, rather than attempting to re-size it. We now know its general form, but [as ever] the real joy is in the details.

Fascinating; I didn't know there was such a thing as water-immersion objectives. Martin . I have no connection with the seller, nor any experience of this paticular model, but there are some 'New Old Stock' Russian water-immersion objectives currently on ebay: https://rover.ebay.com/rover/0/0/0?mpr...

Thanks for the link, Rylander

They also made a K1,2 and 3 for conversions to other 'scopes, such as a change in distance from field iris some 'scopes had.... leitz condenser adapter lenses.JPG .

A few photos ...

There is a Chinese made stereo microscope made to look very much like an Olympus; almost identical. I recall is being a 4.5x but my memory could be wrong. It may well have been made for Olympus at one time, or another. Things have gotten muddy. For the past 15 or 20 years, as major microscope mfg. ...

Thanks for the photo ... and apologies for the delay in posting pictures of mine. Having seen the current price of phototubes and 'video' adapters on ebay, your $100 sounds an absolute bargain !! I am becoming increasingly sure that mine might be a Scienscope [or similar] https://www.scienscopeprodu...

Thanks, hkv That was my original suspicion I'm very happy with my purchase, but there is always that nagging doubt. Memory fails me regarding the detail, but; I'm sure that I recall hearing that certain instruments from another "manufacturer" came off the same production line as the Olympus equivale...

Thank you for the comments, BillT I will post some photos in the next couple of days, but; quite honestly, it looks exactly an Olympus to me ... except for the lack of any branding and the two features I mentioned. http://www.alanwood.net/downloads/olympus-sz30-sz40-sz60-sz11-brochure.pdf MichaelG.

Greetings, Microbe Hunters . I have recently purchased what appears to be an Olympus StereoZoom microscope, in almost 'as new' condition. ... The original owner purchased it in 2004, at which time it was described as "unbatched". There is no serial number visible, and no Olympus markings anywhere on...
