Without extensive testing both finite (BH) and infinity (BX) counterparts, which I have not done, I would not be able to state whether they are optically "identical". However, simple condensers that do not use phase rings, DIC prisms etc., like the condensers that only provide brightfield and darkfi...

Just a heads-up that I am selling several microscope parts (as well as camera lenses and specialty lenses) on photomacrography.net. The rules are pretty much the same as on MicrobeHunter, as far as I know. See: http://www.photomacrography.net/forum/viewtopic.php?f=30&t=45957 http://www.photomacrogra...

[...]Maybe transparent plexi display case might look great, but a bit impractical as it would need to be huge.[...] I have considered a lighter alternative. Plexiglas (= acrylic) is quite heavy and a bit expensive, but the best DIY stores sell lightweight semi-transparent plastic panels with hollow...

The German https://rotri.de/ makes dust covers to measure. You design them in the tool they have available on their web site, then after a few days you get them by mail. They are neither transparent nor semi-transparent, but made of a relatively thin, grey non-woven synthetic cloth that seems to be ...

Thanks for the suggestions. Another term I just found is "fine focus rubber boot". My interest in this "thing" at the moment is to reversibly connect a stepper motor to the fine focus knob of an Olympus BX-50 without any modification of the microscope. I am building an adjustable stand for the motor...

I wonder whether the "rubber focus knob cover" often added on top of the fine focus knob of a microscope to provide a more precise/more comfortable handling of the fine focus has a specific name. I am aware that "rubber focus knob cover" is occasionally used for microscopes, but I would like to know...

There is a ton of legitimate research around nanotech as delivery agents for drugs, including the so-called "vaccines." They have been working on the stuff for decades. Carbon nanotubes, graphene oxide ribbons, nano-antennas, nano-bubbles, quantum dots, graphene hydroxides, and so on. They are all ...

It seems to be a Zeiss Stereomicroscope III.

I have a page on this model on my site (note that it is the second picture from the top, not the first): http://www.savazzi.net/photography/zeis ... mic_3.html

I don't have the above Schott lens, but comparable no-brand ones. Mine, at least, contain only a planoconvex lens with the flat side facing toward the end of the light guide. The latter is placed at approximately f distance from the lens (where f is the focal length of the lens). There is no diffuse...

Great review, thanks Enrico ! Is heatsink directly attached to the faceplate for the better heat transfer ? How are vibrations from fans ? No, the heatsink is attached to the mostly plastic collet and mount for the light guide, which in turn is attached to the front panel. The clamp for the optical...

Thank you for sharing the informative review again (I have previously read other reviews from you and found them helpful)! How do you connect this LED light to your BX50 scope, do you place its fiberoptic output end directly to where BX50's light bulb was? I have not done it yet, but have some part...

Apparently no members have tested this illuminator. I now posted my review of the 50 W model on my web site:
http://savazzi.net/photography/amscopeled50w.html

Does anyone have a hands-on experience with the current Amscope LED fiberoptic illuminators? I am considering the 50 W model which is not excessively expensive compared to other brands (I need plenty of light for DIC, darkfield, epi illumination etc. on stereomicroscopes, photomacroscopes and compou...

. They used to cover microscopes with glass domes - might be worth looking into https://www.ebay.co.uk/itm/Large-Glass-Dome-Cover-Cloche-Display-Height-50-cm/323861482909 A glass dome would work for a small microscope, such as a teaching-level stereomic. A glass dome big enough to contain a large s...

I have given some thought to the problem of covering my microscopes, but so far have not acted because we have been moving frequently the past few years, and did not want to increase the amount/volume of our stuff to pack and move. So far I made do with large (almost single-blanket size) blue pieces...

I had good results by plucking a handful of dry moss off a granite boulder in a public area in Stockholm, Sweden, in the autumn or early winter. I placed it in a small translucent polypropylene jar and filled 3/4 of it with tap water, then left the closed jar a few weeks on the window sill where it ...

I have the exact same stand and coarse focuser. Mine came with a monocular head and a ~3x long-working-distance objective that look typical for a mechanical shop microscope (although I guess they could also be used for hardness tests). The optics were not particularly good, and chromatic aberration ...

[...] Why is serious amateur microscopy not in the mainstream as it was 100-150 years ago? At that time, and earlier during the Victorian period, well-to-do people were expected to cultivate wide-ranging interests in science, history, literature etc. For example, see Lynn Barber 1980: The heyday of...

Are you sure you need the Photomicro Adapter L? I was under the impression that this was only for the finite era Honestly I’m not sure at all. Would anyone be able to shed more light on this? I suppose it would be necessary to use the adapter if using a photo eyepiece as Scarodactyl suggested. With...

P9080003c.JPG A colorful example of delamination of some internal optics of a Zeiss Photomicroscope (probably one of the telan lenses of the magnification changer, or one of the optics for the film camera built into the stand). I had been gradually building up and completing this microscope for sev...

So far, transmission optical microscopy has not been one of my main interests, but now that I am retired and will have more time to spend on my hobbies, this might change. I worked over 30 years as a university researcher and teacher in geosciences in a handful of countries, mostly Sweden. Functiona...
