Looks like a pancratic condenser from Zeiss Jena.

The company Karl Kaps Wetzlar still exists and still makes microscopes, but very special ones.

The turret units of Ortholux II and Diavert are interchangeable.

I was looking into imaging solutions for a labphot (that I don't have, fictitious dry run) to fuji xe2 (that I do have). LMscope says more than $1000.

LMscope is insanely expensive with everything they offer.

Bought from Aliexpress twice. The first time and the last time. It was a low value item, some adapter ring RMS to M42. It was explicitly advertised as RMS to M42x1 but what I got was RMS to M42x0.75 (aka T2). The printing on the adapter stated M42x1 but the thread was 42x0.75. Aliexpress asked me to...

Should I keep this intact, or salvage the objectives?

Keep it intact! This scope is mechanically far superior of any Swift product. The objectives might be a poor fit on the Swift anyway.

This looks like a Will BX100 made in the 70th to the mid 80th. Will was acquired by Hund Wetzlar in 1988, a Company that today still makes microscopes. Hund support staff is quite friendly and helpful to amateur microscopists. The BX100 is a scope of very good build quality but was designed for 37 m...

Also are all PHACO objectives dual purpose, that is Phase and Florescence or are those two separate? I've seen some PHACO 10,40 and a PHACO FL 70 oel all 170mm. While you can use any objective for fluorescence work you may experience a rather weak picture. Fluorescence demands objectives with high ...

It depends on what you are doing. The Leitz 2.5 is nice in bright field but terrible in fluorescence for example.

On the fence whether to keep a 25 0.65

Just send it to me and make me happy.

Try https://www.laboratoriumdiscounter.nl . They sell to individuals everything the laws permit. I don't have any idea about Swiss import restriction, though.

This list is all 170 mm.

Leitz changed from 170 mm tube length to 160 mm end of the seventies. Eye pieces without the field value are generally made for 170 mm tube length while those with it are for 160 mm. A "Periplan GF 10x" is for 170 mm. A "Periplan GF 10x18" is for 160 mm. You can use 170 mm eye pieces on a 160 mm sta...

It will not work.

Quality and even more cleanness is quite an issue with slides. You may get terrible ones from great European names and good ones from China. Next order it may be the exact opposite. If the slides are just dirty I simply clean them in the dishwasher. If there are irregularities in the glas itself I s...

One question... this has a max of 40x... is this enough for rocks and leaves and whatnot? In theory could you put 20x eye pieces and get double the magnification? And another question can a canon dslr eos be mounted on that trino? I own a stereo with 10x 20x and 40x and rarely use the 40x. 10x is o...

This one gives you a camera port. Its mayor shortfall is free working space.

Just a quick and dirty sample for microscope fluorescence. This picture is taken with blue excitation from with epi-illumination. It shows some cut through a tuja wipcord needle. Picture out of camera, just reduced in size for the forum.

Most of the dyes used to stain plant cuts produce significant fluorescence if excited by blue light. A 50W halogen lamp is enough for that. Fluorescence stain are considered dangerous because they couple to DNA with makes them suspicious to promote cancer. On the other hand a careful person doesn't ...

The problem may be your eye-piece adapter. They are quite afocal. The issue increases with the power of the objective. A 100x objective may simply be out of focus. Try a dry and well fixed sample without cover glas. This allows the objective to be closer to the sample. About LiveView: LiveView alway...

Here you can find information on the electonic first shutter curtain menu setting: https://www.digitalcameraworld.com/au/tutorials/canon-school-set-up-your-canon-eos-camera-for-silent-shooting In higher magnifications the shock of the shutter is enough to blur the image. Thanks for helping me about...

A HBO 50 ist enough for most professional application.

The 40x is a no-brainer, but I'm wondering if I might be better served with the 60x PLAN for this scope vs. the 100x oil PLAN. Any opinions? Dry 60x objectives are quite difficult animals. They are very sensitive against coverglass thickness and other variables. An immersion objective is in fact mu...

Looks like a very nice microscope. Is this a rotating stage?

Be careful! Is this 1$-plug really designed to accept currents up to 8 ampere?

I was wondering about this... Could you explain why I couldn't get it working again?

I considered you want to restore the original condition.
It will be quite hard or even impossible to find the missing parts.

You could build some self made stand and lightning system, of course.

you will never get a working microscope out of this. But it contains some quite valuable parts like the mirror device, the ocular and the objectives.

Best is to sell this components and buy some microscope with the money.

You will barely find them in dry dust or in carpets. Use a knife to penetrate an old mattress and look for areas not exactly dry. This is where you will find them.

You can use them on a 160 mm microscope together with oculars designed for 160 mm tubes. Best results are achieved with Leitz Periplan oculars. Objectives weaker than 16x may not be perfectly parfocal but this is not a big issue. Many people including myself mix 160 and 170 objectives on the same mi...
