Introduction to Widefield Microscopy
This article gives an introduction to widefield microscopy, one of the most basic and commonly used microscopy techniques. It also shows the basic differences between widefield and confocal…
Photoactivatable, Photoconvertible, and Photoswitchable Fluorescent Proteins
Fluorescent proteins (FPs) such as GFP, YFP or DsRed are powerful tools to visualize cellular components in living cells. Nevertheless, there are circumstances when classical FPs reach their limits.…

Investigating Fruit Flies (Drosophila melanogaster)
Learn how to image and investigate Drosophila fruit fly model organisms efficiently with a microscope for developmental biology applications from this article.
Acousto Optics in True Confocal Spectral Microscope Systems
Acousto-optical elements have successfully replaced planar filters in many positions. The white confocal, regarded as the fully spectrally tunable confocal microscope, was not possible without this…
Video Tutorial: How to Change the Bulb of a Fluorescence Lamp Housing
When applying fluorescence microscopy in biological applications, a lamp housing with mercury burner is the most common light source. This video tutorial shows how to change the bulb of a traditional…
Video Tutorial: How to Align the Bulb of a Fluorescence Lamp Housing
The traditional light source for fluorescence excitation is a fluorescence lamp housing with mercury burner. A prerequisite for achieving bright and homogeneous excitation is the correct centering and…
Fluorescence Correlation Spectroscopy (FCS)
Fluorescence correlation spectroscopy (FCS) measures fluctuations of fluorescence intensity in a sub-femtolitre volume to detect such parameters as the diffusion time, number of molecules or dark…
Image Processing for Widefield Microscopy
Fluorescence microscopy is a modern and steadily evolving tool to bring light to current cell biological questions. With the help of fluorescent proteins or dyes it is possible to make discrete…
