Different types of microtomes for microscopy
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.
What should I do if I want to observe fungi?
Fungi can be interesting to observe, but not all of them are healthy and molds that have spoiled food are particularly a problem.
How do you make dry-mounted permanent slides?
Dry mounted permanent slides do not use a liquid mounting medium. The cover glass has to be held in place in another way.
I can not see any water organisms! What am I doing wrong?
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.
What is Rheinberg illumination?
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.
What are possible reasons for not seeing an image?
In this post I will outline some of the reasons why no clear image can be seen under the microscope.
What can I do if I see a double picture?
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.
How do I correctly observe a specimen?
Before looking at the specimen, we have to make some basic adjustments to the microscope.
What are the differences between brightfield, darkfield and phase contrast?
I also talk about Polarization, Oblique illumination, Rheinberg Illumination, DIC, and fluorescence microscopy.
A Projection Screen for Microscopes
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.
