I bought a number of them over the years. Some of them make claims to be 1,000 power. Actually the magnification comes from how close the subject is from the lens. These pictures of my stage micrometer were taken with the camera sitting on top of it, as close as you can get. The most magnified pictu...

I was buying digital microscopes for a while. I was touting the images I obtained as micrographs. I tested the digital microscopes I have against a stage micrometer and retuned a startling conclusion. They don't resolve like microscopes. These are as magnified as they get. One brand is slightly stro...

How you holding up in the Pandemic, homie?

Using top-stage sidelight in a dark field.

great pictures. I see these all the time. I figured they were some kind of paramecium, but really didn't know.

Fantastic (and nightmarish) video.

I want to thank this website for the stimulation and motivation to learn new things. My microscope has no filter holder. Thanks to your suggestions, I developed a substage shelf over the light source that I can put "filters" on. My filters are very primitive. I mounted small shapes on microscope sli...

I'm awe inspired.

Thanks for these ideas. I didn't think of the coin idea at all.

I'm a newbe. I hope you don't mind this thread.

Neat work. Let me ask, How would you describe the effects of these cut profiles? I found if I just block part of the light with a rectangular card, I can adjust the dark field quite a bit.

Thanks rnabholz. This simple playing around can greatly amplify what I can do with the microscope.

Starting with rudiments.
I made a cardboard tube and put it around the light source. Then I put a piece of carboard on top of the cardboard on top of the tube. As I move the cardboard across the tube I get some dark field effects. (well you get the idea)

Neat thinking. I can put a filter right on top of the light source itself!

Thanks MicroBob. You are an inspiration.

My microscope does not have a filter holder. The "diaphragm" is just a series of various sized holes above the lamp. It there any way I can add a real filter holder so I can get a real dark field image?

I honor these shots! How did you do this?

I use different lamps. This LED light is for taking macros with a camera. I had an old bricked camera I mounted it on to hold it. I used to have it taped to the arm of the microscope but I took it off. It was clumsy.

I made thin sections of a banana peel. The cell structure was clear on the outside but fairly chaotic on the inside.

Does the use of a top stage light with the bottom light minimized count as dark field illumination? It looks like it.

My microtome cuts weren't so good. I may have cut a few cells widths. I was able to see cell organelles (and some motion in them).

Those are impressive. I can never see the cilia.

WoW!

Where do you get one of those blades?
