At the recent Focus on Microscopy 2018 meeting in Singapore, LaVision Biotec and Lastek exhibited the Ultramicroscope II Light Sheet Microscope in a live demonstration at their booth. 

The bidirectional triple light sheet technology of the UltraMicroscope II generates 6 focused light sheets to excite samples from the side while the fluorescence light is detected by a sCMOS camera perpendicular to the illumination plane. Moving the sample through the light sheet generates a 3D image stack. Selective excitation of the focal plane reduces bleaching and photo toxicity significantly. The open setup allows the analysis of cleared samples in any clearing solution or in aqueous media. The dynamic horizontal light sheet focus guarantees excellent Z-resolution covering the entire field of view.

LaVision’s new DaVis 10 defines a new landmark of cutting-edge innovations in Intelligent Laser Imaging software. Combining high-performance cameras with outstanding image processing algorithms opens new dimensions for your imaging applications. DaVis 10 has been redesigned from the ground-up to deliver a software for modern demands for usability, data handling and visualization.

The Laser Quantum axiom 660axiom 660 laser has a new architecture that delivers high CW power whilst incorporating all of the active optics within the laser lead. The axiom lends itself to easy integration into equipment due to its ultra-compact power supply unit, without the complexities associated with fibre delivery.

The axiom 660 is ideally suited to a range of applications including Particle Imaging Velocimetry (PIV), Raman imaging, and a wide range of fluorescence imaging techniques. The high-power enables a brighter image in PIV and imaging of Raman emission over a larger area. With its high power, excellent beam characteristics and size, the axiom 660 addresses several fluorescent dyes including Atto 647N and Atto 655 for fluorescence imaging and super resolution microscopy.

"Expansion microscopy evolved as an interesting alternative in the field of super-resolution microscopy by physically expanding the target sample to increase its size by a multiple and to subsequently image the sample by conventional fluorescence microcopy. But the quantitative determination of the expansion factor remains challenging, since microscopic measurement standards are missing.

Here we use DNA nanorulers in combination with expansion microscopy to expand the fluorescently marked rulers in 2D and to determine the intermark distances before and after expansion. We compare macroscopic and microscopic expansion factors where we found substantial deviations, which should be considered for the quantitative discussion of expansion microscopy data of biological cells and tissues.

Sentinel-5 precursor flying Tropomi, Credit: ESA

 Congratulations ESA on Sentinel-5P take off

Fascination space - after the launch of the Mars Rover in November 2011, nanoplus lasers are again part of a prestigious space project. This time, nanoplus lasers are on board the TROPOMI (Tropospheric Monitoring Instrument) which is the single payload of the Copernicus Sentinel-5 Precursor satellite.

nanoplus has congratulated the project team under The Netherlands and ESA aegis to the successful launch of its Copernicus satellite on October 13th, 2017, from Plesetsk, Russia, saying: "We are excited that our lasers are part of this important mission on monitoring air quality around the globe. According to the project motto 'Observing our future', we will follow Tropomi's results with great interest."

The T-SPEC Real-time Terahertz Spectrometer offered by Ekspla is a powerful tool for investigative applications of pulsed terahertz waves. With simple and robust design, it is easy-to-use and adaptable to individual requirements. The unique design of microstrip photoconductive antenna fabricated on low-temperature grown GaAs substrate ensures broadband spectral coverage and high dynamic range. The system is designed with two delay lines: fast and slow. Fast scan line allows real time data acquisition with 10 spectra/s speed and 110 ps time window. Average of collected spectra can increase dynamic range to 70 dB at pulse maximum and extend spectral range up to 4.5 THz. Additional slow delay line allows combination of multiple time windows; thus spectrometer obtains excellent spectral resolution < 2.5 GHz. The fast scan line is designed without bearings and uses a magnetically coupled drive which makes it extremely reliable and significantly extends the lifetime. T-SPEC spectrometer has hermetic housing with mounted gas inlets.
