5 Rules of buying a microscope
I’ve been repeatedly asked for advice concerning the purchase of microscopes of hobby and amateur purposes. The following rules should help you in your choice. Rule 1: Be weary about “department store” microscopes Enthusiasts who want to pick up the hobby frequently encounter their first microscopes in department stores and toy shops. If you are [...]
Bacteria in phase contrast
About phase contrast Bacteria are transparent and therefore difficult to see using regular bright-field microscopy. The bacterial cells will appear just as bright as the surounding medium and there is no color contrast. Phase contrast optics provides a solution. Phase contrast optics convert the differences in optical density (i.e. the refractive index) of the bacterial [...]

Timeline of Microscopy
The development and history of the optical microscope was one which stretched over a long period of time with many larger and smaller contributions. The following list highlights some of these milestones.
Increasing Contrast using Optical Methods
Many microscopic specimens are either very thin or transparent or lack color. They lack contrast and can not be easily seen in bright microscope light. In many cases it is not possible or desirable to chemically stain the specimens. In this case, optical techniques become necessary to enhance contrast.
