Here I show you a rotating microtome and two table microtomes. The rotating microtome is large and heavy and used mostly in histology. The two table microtomes have a different working principle and are also suited for amateur microscopy use.
Fungi can be interesting to observe, but not all of them are healthy and molds that have spoiled food are particularly a problem.
Dry mounted permanent slides do not use a liquid mounting medium. The cover glass has to be held in place in another way.
Pond water is a favorite sample to observe. Sometimes, you do not see anything, however. The reason is usually that you took a sample from the water itself and not of the ground.
Rheinberg illumination is a variation of darkfield. Rheinberg filters are placed into the filter holder of the microscope, which produce a colored image of the specimen on a background of a different color.
In this post I will outline some of the reasons why no clear image can be seen under the microscope.
Seeing a double picture can be the case when using stereo microscopes or compound microscopes with a binocular head. This can be due to several reasons.
Before looking at the specimen, we have to make some basic adjustments to the microscope.
I also talk about Polarization, Oblique illumination, Rheinberg Illumination, DIC, and fluorescence microscopy.
Projection screens are useful if several people want to look at the specimen. The screen is mounted on the trinocular head instead of a camera.
