Description
The pco.edge 6.2 LE can be considered as the successor of deep-cooled CCD, long exposure cameras. Its design is optimized to realize long exposure times from miliseconds to minutes or even up to one hour. The image sensor is thermally stabilized at low temperatures of down to -20 °C in order to reduce the dark current to a minimum. Together with a high full well capacity and the wide range of exposure times, it is suitable for a broad field of low-light imaging applications like fluorescence, chemiluminescence, or astronomy.
The pco.edge 6.2 offers the following key features:
- wide exposure time range: 1 ms up to 3600 s
- Extremely low dark current
- Global shutter
- High resolution: 6.2 MPixel
- no glow modification
- deep-cooling as low as -20°C

Silicon carbide (SiC) is a wide bandgap semiconductor, which is especially used for high-power, high-temperature and high-frequency devices due to its high energy efficiency. Despite great improvements in the material quality of SiC substrates and epitaxial wafers within the last years, critical defects like stacking faults (SFs) and basal plane dislocations (BPDs) can still lead to bipolar degradation and finally to complete failure of the device.
Ellipsometry is a non-destructive, optical technique for surface characterization. Imaging Ellipsometry in particular combines traditional ellipsometry with optical microscopy and thus enables ellipsometric studies with a lateral resolution down to 1µm. Therefore, it is perfectly suited to study structured or very small samples such as MEMs, FETs, Biochips or flakes of 2D-Materials. 
Microarrays are versatile tools for high throughput screening. Nevertheless they are severely limited. Either the molecules are synthesized in-situ directly on the surface or in-vitro or in-vivo produced externally and then transferred onto the surface. In-situ synthesis shows low yield in terms of purity and restricts therefore the biomolecule probe length to ~50 bp for light-synthesized DNA (Affymetrics) or ~200 bp print-synthesis (Agilent), but allows up to millions of spots per array. Ex-array synthesis on the other hand provides high-purity molecules, but the (bio)synthesis and purification of these molecules is tedious, time consuming and expansive. Also the printing process takes time. Even if one spot can be made per second 100,000 spots will take more than a day. Therefore the idea arose why to copy microarrays. Why not make DNA, RNA and protein microarrays as high quality copies of a high quality original? It worked fine for text books and images. So why not apply it for DNA? Why not build a biomolecule copying machine? A biomolecule xeroxer? 
Light sheet fluorescence microscopy has previously been demonstrated on a commercially available inverted fluorescence microscope frame using the method of oblique plane microscopy (OPM). In this paper, OPM is adapted to allow time-lapse 3-D imaging of 3-D biological cultures in commercially available glass-bottomed 96-well plates using a stage-scanning OPM approach (ssOPM). 
The application shows that the mode and dynamics of trypanosome locomotion are a trait of life within a crowded environment. Using high-speed fluorescence microscopy and ordered micro-pillar arrays we show that the parasites mode of motility is adapted to the density of cells in blood. 
Large-volume volumetric flow experiments and their results: The first of these, investigating a thermal plume at low velocities (up to 0.35 m/s) demonstrates the abilities and requirements to reach volume sizes up to and probably beyond one cubic mete
