Re: Fusing glass slides

Thank you everybody. @Scarodactyl,I do like the idea of the mini forge with the attached microscope- I don't know if I would ever figure out how to use it, but it would be fun to try. I've never used the glass water- interesting. This is for the light sheet microscope. The proper containers are larg...

Fusing glass slides

Anybody have any experience fusing microscope slides together to make a little glass box, like a mini-aquarium? Can't glue it together because it will have strong solvents inside that will destroy adhesives or sealer. There are places that will custom-manufacture something like this, but the cost is...

Re: Newbie with information overload looking for first microscope

I know this in an ongoing discussion. I remember my professor in college debating which microscope to buy for his children, whether children need less magnification than adults. Everyone is making valid points. I had four kids, all grown up now. We had a Meiji Stereomicroscope in our house. We found...

Re: Axiomat Aperture Slide

Ah, the Aperturblendenschieber! (It's sounds much more scientific if it's in German.)
I've never taken mine apart, so it's interesting to see what's inside.
Due to the Box-like shape of the Axiomat, the control knob has to be so far from the light path.
Thanks for taking yours apart!

Re: Zeiss Tessovar

It was designed to have a beam splitter tube with an eyepiece for focusing and metering. That's not really necessary when using an SLR or video camera because you can focus through the camera. But, the binocular head for the Zeiss Standard fits perfectly on the upper dovetail and can be used for vie...

Re: Fluorescence and filter cubes

I agree with microBob. We have eyepieces on several of the microscopes in my lab at work, but we don't use them. We always work through the monitor. Especially with fluorescence. We do still use the eyepieces on the stereomicroscope for procedures on mice. The assistant watches through the monitor t...

Re: My Zeiss Axiomat

I'm guessing of the 650 or so Axiomat microscopes that were produced, more than a few ended up in a landfill at the end of their commercial life. I wonder how many are still around? They were originally intended for Biomedical Applications. It turned out they were just too expensive. Some of the pre...
