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 serious about [...]
Bacteria in phase contrast
The four pictures on the right show different bacterial species 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 [...]

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.
Electron Microscopes vs. Optical (Light) microscopes
This post outlines the advantages and disadvantages of electron microscopes in contrast to optical (light) microscopes. Each type of microscope is designed for different areas of applications.
Drawing Microscopic Images
Drawing is still a useful method for documenting microscopic specimens, despite advances in (digital) imaging technologies. There are certain advantages in drawings that photographs do not possess.
