The stage caliper allows you to move the slide with a precision of 0.1mm. In this video I explain how to read the scale.
Here we have a look at the different parameters that characterize microscope eyepieces: size, magnification, eye relief.
The differences between magnification and linear magnification. The basics explained.
You need to take a picture of a reference (micrometer slide, ruler, etc) and then measure out the number of pixels.
An intro video into stereo microscopes.
Standing water is a good source of microorganisms to be observed under the microscope.
Here I put some mold under the microscope. The spores are visible in bright field as well as in phase contrast. I also look at it using my stereo microscope.
Some fibers in brightfield and darkfield. The fibers have a diameter of about 0.015mm. They are thinner than the cells of some algae. At the end of the video, I superimpose the images of the algae and the fibers to Read More …
Pretty sad. 🙁 The ciliate paramecium was squashed to death between the microscope slide and cover glass….
This is a very simple, yet effective way of making cell surfaces visible. Here I am making a glue impression of a leaf surface. The stomata are visible under the microscope.
