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…
Sub-Femtolitre volume_Fluorescence correlation spectroscopy (FCS)

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…
CARS image of cellulose fibers. The fibers are visualized through the C–H vibrations of the polyglucan chains in cellulose.

CARS Microscopy: Imaging Characteristic Vibrational Contrast of Molecules

Coherent anti-Stokes Raman scattering (CARS) microscopy is a technique that generates images based on the vibrational signatures of molecules. This imaging methods does not require labeling, yet…
Cleaning microscope optics

How to Clean Microscope Optics

Clean microscope optics are essential for obtaining good microscope images. If they are dirty, the microscope should be cleaned to avoid a loss of quality. If you decide to do this yourself, you…

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…
