Re: BX41 focus assembly

I have a PDF of the BX41 Frame Repair Manual, but it does not contain anything about the focus mechanism. I have a PDF of the BX51 / BX52 Frame Repair Manual that has some illustrations and notes about the focus mechanism, but I do not know if it is similar to the BX41. Let me know if you would like...

Re: Victorian Micro Artwork

A modern practitioner, Klaus Kemp, sadly passed away in 2022. He was a regular exhibitor at microscope club meetings in Langton Matravers and Reading, where he showed the equipment that he used and let us try arranging diatoms. You can see some of his work in a Google search: https://www.google.com/...

Re: correct tube length for two finite metallurgical objectives

According to my table of Olympus objective designations, your LWD MPlan lens is corrected for a 210 mm tube length.

Re: Affordable options to mount Nikon on Olympus SZ61

The vertical tube on the Olympus SZ61TR was designed for attaching a DP12 camera which has a 1/1.8 sensor; I think this is about 9mm diagonal. sz61.jpg This is much smaller than a Micro 4/3 sensor, 22.5 mm diagonal, so I don't think you could attach a digital SLR or mirrorless camera unless you use ...

Re: what kind of filter could it be?

45 mm is the diameter of filters that fit the light output on the base of several Olympus microscopes. I have a real Olympus A-POL linear polariser and also a look-alike that does not have a name on it and that is very similar to yours. olympus-polariser-analyser-700.jpg Olympus A-POL polariser (lef...

Re: First purchase advice

Alan

There are two microscope clubs in East Anglia where you would get a warm welcome and lots of advice, the Anglian Microscopy Group and the Iceni Microscopy Study Group.

Re: FAQ--which Olympus objectives are good for macro work, and which are not?

If anyone wants to compile a list of the BX-era UIS and UIS2 objectives, I have a couple of PDFs of catalogues with lots of information to get you started.

Here is an explanation of the abbreviations on Olympus objectives:

Re: Leitz Orthoplan - bringing it back to life

Methyl hydrate is another name for methanol or methyl alcohol, so it is an alcohol.

Re: Klaus Kemp slides

Nigel Williams is slowly selling Klaus Kemp's slide collection, with all proceeds going to Klaus's family.

He is also selling them at occasional meetings in England, see for example at the end of this page:

Re: can anyone id these please?

Bradford is not far from Leeds, so perhaps you could take the items to a meeting of the Leeds Microscopical Society, where someone might be able to help.
