Delmic and Phenom World announce DelPhi, the world's first integrated tabletop fluorescence and electron microscope. Delmic produces high performance, user friendly, integrated solutions while Phenom World is a leading producer of electron microscopes. The DelPhi is a complete solution that makes it possible to do fast correlative microscopy with high overlay precision. The system is easy to use for both optical and electron microscopists and makes correlation intuitive and fully automated.

Coupled three-dimensional Ge quantum dot crystals (QDCs) are realized by multilayer growth of quantum dots (QDs) on patterned Si (001) substrates. With increasing the vertical periodic number of the QDCs, the photoluminescence (PL) spectral linewidth decreased exponentially, and so did the peak energy blueshift caused by increasing excitation power, which are attributed to the electronic coupling and thus the formation of miniband.

A high-speed scanning solution for transmitted-light microscopy which allows scanning of microtiter plates at unprecedented speed was developed at the Fraunhofer-Institute for Production Technology IPT in Aachen, Germany. The novel solution is based on a continuously moving scanning stage with synchronous z-position adjustment and flash illumination.

In the past two decades, light microscopy has seen a tremendous improvement with super-resolution techniques. Many of the super-resolution microscopes (3D-SIM, STED, and PALM/STORM) are now available in a commercial solution, and are entering labs and facilities worldwide. This offers an important step forward in the field of research in biology, but when not used in optimal conditions, those powerful techniques can give rise to artefacts. Here we focus on parameters that can deeply influence the image quality for 3D-SIM and the next challenges for this technique.

The 14th European Light Microscopy Initiative (ELMI2014) conference will be held in Oslo, Norway from May 20-23, 2014. ELMI is an internationally recognized meeting on Light Microscopy and offers a unique combination of lectures, exhibitions and hands-on workshops organized by leading microscopy companies. The meeting is aimed at a life sciences audience and specifically focuses on close collaborative interactions between companies, developers and researchers. Imaging methods from a wide range of research fields will be presented that are relevant to both new and expert users of electronic and photonic methods.

A novel optical concept for a spinning disk confocal microscope is presented, which warrants maximal optical quality, speed and usability. It employs a single disk only instead of two, and it uses micromirrors instead of microlenses, thus minimizing chromatic aberrations and yielding an uncompromised performance over the full visible range from 405 - 700 nm. Careful optimization of coupling optics result in flat and homogenous illumination free of speckle artifacts, and the full optical performance is maintained over the full field of view.

In contrast to fluorescence methods, bioluminescence microscopy does not need excitation by light. As photon emission results from a chemical reaction, results are highly specific and quantifiable. Until recently bioluminescence microscopy was difficult to approach as a result of rather dim signal intensities. Due to better probes and especially thanks to better and more specific instrumentation this technique has now become much more accessible and can in many situations outperform fluorescent approaches.

Scientists at the Campus Vienna Biocenter (Austria) have found a way to overcome some of the limitations of light microscopy. Applying the new technique, they can record the activity of a worm's brain with high temporal and spatial resolution, ultimately linking brain anatomy to brain function. The journal Nature Methods publishes the details in its current issue.

The ability to efficiently and reliably locate and image an area of interest in a larger three dimensional sample remains a very challenging application in advanced microscopy. Approaches to address this issue include dedicated sample preparation steps to cut out the target area, or optical penetration using dedicated confocal systems. Both approaches are labor intense and cannot be automated easily. With X-ray microscopy, a new technology has evolved that shows a huge potential to bridge the gap between light and electron microscopy.
