Re: Need 28mm eyepieces

I really must thank you for all of your input. I am located in Victoria, British Columbia, Canada. Were you thinking that you might have a set of appropriate eye pieces? Please feel free to send me a PM/DM.
Thanks very much,
Don

Re: Need 28mm eyepieces

Well, that was a great try with respect to the Reichert eyepieces, but they turned out to be 28.9 mm in OD vs my sleeves which require something less than 28.12 mm. I have therefore ordered a couple of adapters for 30 mm to 23.2 mm and will turn them down to fit. Now to acquire a couple of 15X 23.2 ...

Re: Need 28mm eyepieces

Thanks, apochronaut, it certainly does take its design cues from that microscope. I appreciate your power of recall. I'm looking forward to getting an accurate value of the outside diameter of the eyepieces that Tatiana (seller at the link you sent) will measure when it is morning her time. I'm keep...

Re: Need 28mm eyepieces

Great comments, apochronaut, thank you. I was measuring the OD of the eyepiece body below the flange. I was actually getting measurements of 1.100 to 1.101" (27.97mm). The ID of the tube it slips into is 1.107" (28.12mm). I would rather not swage the tube but will check out the Reichert Austria that...

Re: Need 28mm eyepieces

No, your suggestion is a good one and one which I have considered. In fact, I have had an eBay search in the works for a few months looking for something like this one which a microscope collector/phonograph rebuilder has: IMG_7066.jpeg The advantage of the swing-away body is that I can more easily ...

Re: Need 28mm eyepieces

My experience with unbranded WF20x/12, 30mm OD inexpensive eyepieces is negative - the view feels "weird" and most of the FOV is blurred or distorted. The best combination IMHO is a 1.5x Barlow lens (if the scope in the picture has this option) with 10x or 15x eyepieces. Together with an on-scope 4...

Re: Need 28mm eyepieces

Interesting comment, Bob. My microscope has a sliding 2x/4x objective (photo attached). Does your comment suggest that I would be better getting 15X eyepieces rather than 20X? A fellow who is knowledgable about microscopes (a collector/repairer) suggested that 80X is a good magnification for examini...

Re: Need 28mm eyepieces

PeteM: Thank you for that suggestion. My current plan is to buy some inexpensive 23.2 to 30mm adapters and turn them down on my metal lathe so they will fit my microscope. (The 28mm I had posted is the O.D. of the eyepieces that came with it). I needed to order a live centre that will support the en...

Need 28mm eyepieces

Hello everyone, First time post here. I am a retired teacher who (a long time ago) used to use stereo microscopes in the lab. The make I have is Erma Optical Works (Tokyo), the objectives are 2x/4x and the eyepieces have tubes which are 28mm (1.10") in diameter. The eyepieces are WF10X. In the (hobb...
