XIMEA, the innovator of small size and high speed cameras, has released more models with Sony CMOS Pregius™sensors and USB3 Vision. It started with models based on IMX174, IMX252 and IMX250, and now XIMEA has made accessible to the general public the first units with Sony CMOS IMX255 sensor providing 8.9 Mpix at 43 Fps - MC089MG-SY / MC089CG-SY, as...

There is no better time to trade in your older metrology equipment for a new state-of-the-art system from ZYGO, or upgrade your current system to increase its capabilities and extend its service life. ZYGO's current products include advanced technology, hardware enhancements, and current generation software and computer platform providing the highest value, reliability and metrology capabilities available today, while lowering...

Mosa creators of award-winning, leading edge, high tech tile for walls, floors and terraces, began barely a year ago to work with SEM, an advanced electron microscopy technology. In that short space of time, however, the device that is the size of an old PC has proved its effectiveness, helping Mosa achieve a significant step in its efforts to research the chemical nature...

Smoukov Reactions inside the pores of metal–organic frameworks (MOFs) offer potential for controlling polymer structures with regularity to sub-nanometre scales. We report a wet-chemistry route to poly-3,4-ethylenedioxythiophene (PEDOT)–MOF composites. After a twostep removal...

Chromatic-dispersion Based on complex spectral analysis of the optical field, the Apex Technologies Optical Complex Spectrum Analyser AP2441B/AP2443B is able to measure the chromatic dispersion and the group delay of a transmission line. This paper is dedicated to explain clearly the measurement method of two examples of a 13.2 km standard Single Mode Fibre (SMF) length using a 10 Gb/s...

Constellation-and-eye-diagram-qpsk This paper depicts the strong contribution of the Apex Technolgoies Optical Complex Spectrum Analyser AP2441B/AP2443B in characterising and evaluating 43 Gb/s DQPSK (Differential Quadrature Shift Keying) modulators thanks to its ability to display the phase eye pattern and the constellation. Low-drive-voltage (3.5 V) and uniform modulation characteristics of MZIs (Mach Zehnder Modulators) were achieved with Z-cut dual-drive nested-MZIs...

MZI-time-resolved-chirp-and-inetensity-measurement The spectrum of a chirped optical NRZ data stream obtained by an external Mach-Zehnder Modulator (MZM) is analysed using the Apex Technologies Optical Complex Spectrum Analyzer AP2441B/AP2443B. We  demonstrate that it is possible to induce chirp without broadening the optical spectrum by employing a MZM with optical power unbalancing in the two waveguides. For standard chirped MZM (different...

Instensity-and-chirp-temporal-parameters-of-a-MZI-modulator The discussion exposed in this paper is based on a synthesis of several elements collected in some publications dealing with fundamental characteristics of Mach-Zehnder electro-optic travelling wave intensity modulators. We draw an analysis of the optical response of these modulators to a time varying drive voltage, modelised after a description of their technological conception. Then we review the...
