These are three different microscopic techniques.
Safety issues in microscopy are not only relevant to amateur microscopists, but also for teachers who want to conduct basic microbiological and microscopic work in a school laboratory. In this case the organisms are alive and depending on the type of organism, they may pose a possible health hazard. The post addresses some of the safety issues that should be taken into consideration.
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.
The home laboratory provides a safe working environment for microscopic investigations.
Here is an instruction on how to calculate the size of cells using a microscope.
There are several methods how bubbles can be reduced when making slides.

This post explains how to make a wet mount. Video included!
Before specimens can be processed for making permanent slides, they may need to be fixed.
The hemocytometer (or haemocytometer or counting chamber) is a specimen slide which is used to determine the concentration of cells in a liquid sample. It is frequently used to determine the concentration of blood cells (hence the name “hemo-“) but also the concentration of sperm cells in a sample.
