QTM B, 1963, the first commercial automated image analysis system for microscope images, based on a TV camera and developed by Metals Research in Cambridge, England.

50 Years of Image Analysis

Modern image analysis systems perform highly sophisticated image processing functions on images from an automated microscope and digital camera. 50 years ago, the first image analysis system was…

Nobel Prize 2012 in Physiology or Medicine for Stem Cell Research

The Nobel Prize recognizes two scientists who discovered that mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. Their findings…

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…

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…

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…

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…

Live cell imaging, 4 colors: Mitochondria (MitoView Green, yellow) and actin (mNeonGreen, cyan) microtubuli (SIR-tubulin, magenta), endosomes (NIR750, green). Processed with DSE and DSE powered by Aivia.

The Principles of White Light Laser Confocal Microscopy

The perfect light source for confocal microscopes in biomedical applications has sufficient intensity, tunable color and is pulsed for use in lifetime fluorescence. Furthermore, it should offer means…
