Recently, Toptica's president Wilhelm Kaenders held a keynote presentation at the OSA Frontiers in Optics Conference in Washington about his vision of the future of quantum technology. He described the "small-company perspective" of the transition from laboratory-only experiments towards large projects with public interests. Read more in this article.

Announcing: 2nd Workshop on Data Assimilation & CFD Processing for PIV and Lagrangian Particle Tracking

workshop

The "2nd Workshop on Data Assimilation & CFD Processing for PIV and Lagrangian Particle Tracking" will take place on December 13-14, 2017 in Delft, The Netherlands, sponsored by LaVision.

Many procedures are nowadays available that increase or enhance the information measured with Particle Image Velocimetry (PIV), Particle Tracking Velocimetry (PTV) resp. Lagrangian Particle Tracking (LPT) or other flow measurement systems using techniques imported from the CFD and applied mathematics community. The advent of time-resolved and volumetric measurements have multiplied the possibilities with much excitement of PIV and PTV development researchers as well as from the applied fluid mechanics community. The methods range from regularization strategies using the (simplified) Navier-Stokes-equation or the use of the momentum equation to obtain pressure from velocity measurements, to variational data-assimilation frameworks using adjoint CFD solvers.

Following the success of the first workshop last year, many positives responses have been received to the organization of the second workshop and two keynote lecturers have been invited:

Prof. Dr. Peter Schmid, Imperial College, London: "Data assimilation and dynamic observers for data-based flow field recovery"

Dr. Dominique Heitz, IRSTEA, Rennes: "Coupling experimental and computational fluid dynamics: synopsis of approaches, issues and perspectives"

Abet announces a new line of QE Measurement Systems

abet

The Abet AB6000 series QE Measurement Systems provide turnkey solutions for spectral characterization. An LED based light engine allows DC to high frequency monochromatic light generation. No chopper or order sorting filters required. The 250 mm focal length, direct drive monochromator offers high scan speed and generous light output. Micrometer driven slits allow reproducible bandwidth control.

The base system includes all the necessary hardware and software. A built in Windows 10 PC allows full control of test parameter settings and instrument performance. PHOTOR software controls the instrument and offers complete data analysis capabilities.  Also included are the required bias light, a bias voltage supply, a DSP powered lock-in amplifier, and I/V converter to separate AC from DC signals and amplify them, all necessary reference and monitor cells, temperature monitoring electronics and as ordered cell mounting and contacting hardware, temperature control, XY translation stages for QE mapping, or Internal Quantum Efficiency Option.

Optional range extension options increase the range of the AB6000 from 350 to 1100 nm to 300 to 1800 nm.

LaVision extended its portfolio to a UV lens designed for optimal performance with intensifiers

3379 2 UV lens 85

One of the main advantages of this lens is the capability of correcting chromatic aberrations.

The selection of objectives with high transmission in the ultra-violet wavelength ranges when working in the field of UV-imaging with lasers or self-emission is quite limited. That’s why LaVision had designed an optimized lens which perfectly matches the requirements of combustion diagnostics and all UV imaging with intensifiers or a UV-sensitive camera.

Besides its capability of minimizing chromatic aberrations with this unique designed UV lens, its low minimum f-number of the lens is a precious benefit for high light collection efficiency. The focal length of 85 mm leads to shorter working distances compared to "standard" lenses.

This UV-lens is perfectly suited for the use with 25 mm intensifiers, resulting in a large image size and an excellent image quality. In addition, it is possible to perform the image calibration in visible light in order to subsequently work in the UV range while maintaining the same focus position.

Ekspla PhotoSonus: Mobile High Energy Tunable Laser System for Photoacoustic Imaging

PhotoSonus series High Energy tunable Lasers for PAT

Following the demand of high output energies in the photoacoustic market for imaging larger volumes of tissue, the Ekspla PhotoSonus, a new high energy tunable laser source for photo-acoustic imaging has been introduced. Time-tested Ekspla nanosecond pump laser, parametric oscillator, power supply and cooling unit are integrated in a single robust housing to provide mobility and ease of use.

Highly flexible PhotoSonus platform makes it easy to be integrated and used in a photoacoustic imaging system: it is fully motorized and computer controlled, have user trigger outputs/inputs and special functions as fast tuning between OPO wavelengths. Parametric oscillator generates output energies up to 200 mJ at peak. Achieving a highly uniform spatial distribution from OPO and adjustable beam diameter helps homogeneously couple various size fiber bundles and deliver balanced energy light to the target. By employing a wide range of other options (like access to OPO idler range, toggling between OPO and fundamental wavelengths through simultaneous output), this laser system can be modified to specific user requirements in order to expand photo-acoustic imaging possibilities.

Nanonics Imaging: Breakthrough Study Sheds New Light on Graphene

Recent Study Demonstrates Innovative Enhanced Graphene Photodetector with Plasmonic Fractal Metasurface 

Graphene is a very promising material for photo detection due to its unique properties, e.g. ultrabroadband optical absorption, ultrafast electron speed, and wavelength independent absorption. However, single layer graphene - with only single atom depth - exhibits very low optical absorption, which limits its application in photodetection systems.

A recent study by Jieran Fang et al, published in NanoLetters, demonstrates a new path forward for significant photo detection enhancement in graphene.  In this paper, which was also highlighted in the February 2017 issue of the American Physical Society, researchers designed a gold fractal metasurface, similar in shape to a snowflake, and measured its electromagnetic character. As part of this study, a Nanonics MV2000 NSOM system was employed for plasmonic characterization of the snowflake metasurface with near field collection mode NSOM.

The obtained results demonstrated strong plasmonic generation near the branches and the edges of the fractal structure. It was demonstrated that the fractal metasurface integrated in graphene photodetector as source and drain provided enhancement factors of over 8-13. Additional advantages of this new enhanced graphene photodetector are broadband and polarization insensitive. This work indicates the great potential of enhanced graphene photodetectors in photodetection technology.
