Have you ever wondered how superresolution microscopy works? What’s the difference between STED, STORM, and MINFLUX? What is “resolution” and what is a “PSF”? What is so special about the STEDYCON? Read on to find out.
If you have any suggestions, questions or ideas for our knowledge base, we would be very happy to hear from you.

You have heard of STED but don’t have a clear idea how it overcomes the diffraction-limited resolution of confocal microscopes? You maybe even think it to be somewhat complicated? In fact, it isn’t. It’s just physics, smartly applied. Details >
The donut-shaped de-excitation beam is one of the most important practical ingredients for superresolution STED microscopy. But how do you put a hole into a beam of light? Surprisingly, it’s not that difficult if you know how to do it, but it’s very difficult to get it right in practice. Details >
What has to be inside a STED microscope to achieve superresolution? How does its hardware differ from a confocal setup? (Hint: Not very much.) And what does that mean for the user? (Many good things.) Is handling a STED system any more complicated than using a confocal? (Not really.) Important questions – here are some in-depth answers. Details >
Since the 1990s, confocal microscopes have been a staple in labs visualizing biological or material specimens. The development of STED microscopy prompted the question: how does the established confocal microscope compare to the (now not so) “new kid on the block”? Details >
Today’s high-end fluorescence microscopy is unthinkable without lasers. Reason enough to take a closer look at these sophisticated light sources. Details >
Aberrations can give microscopists a hard time. They belong to microscopy like pathogens belong to life. There are ways to bring diverted rays back on track, but some are better than others. The question is: deformable mirror or correction collar? Details >
