  • CEP Stabilised Systems

    Laser Quantum Ltd.

    With pulse durations approaching the single cycle limit, the phase relationship between the carrier and its envelope becomes increasingly important. Controlling the carrier envelope phase (CEP) enables the exploration of a whole new area of extreme nonlinear physics where the relationship between the phase of the carrier wave and its envelope becomes crucial to the observed phenomena, e.g. in attosecond physics, where the front end of the machines generating isolated attosecond light pulses traditionally are based on CEP-stabilized oscillators. Another field which has opened up is the exploration of CEP dependent effects in electron emission spectroscopy, or more generally in the field of nano optics, plasmonics and femtosecond electron point sources.

  • Color Measuring Unit

    Colorette 4 - Probat Burns

    The Colorette 4 serves for precisely measuring the colour of ground roasted coffee. By means of the stripping device, the sample to be measured is prepared and afterwards positioned at the measuring point. The Colorette works according to the principle of reflection measurement. A ground coffee sample to be measured is illuminated with a white clock-pulsed LED. For colour value determination, the reflected light is thereby captured by a sensor. The determined colour value is afterwards indicated on the touch screen. The indication in different scales makes it possible to use the device flexibly and to adapt it individually to the requirements. Thanks to the improved components, the Colorette 4 is low-wear and guarantees most exact measuring results during the entire lifetime. The extended connectivity offers various integration possibilities into processes and systems.

  • Compact Measurement System For Steel Wire And Rods With Small Diameters

    LAP GmbH

    A glowing hot wire is pulled through the rolling mill at about 120 meters per second during ongoing production. Speed, high temperatures and dirt are special challenges for a high-precision measuring system. Our solution is the Contour Check Wire. It is specially designed for the geometric measurement of wires, rods and rebar and, at 800 Hz, offers the optimum measuring rate for accurate data acquisition. In the uniaxial version, you can check the diameter; in the two- to three-axis version, the ovality can also be determined. The small dimensions and light weight allow a quick and easy integration of the Contour Check Wire into the existing line.

  • Complete Testing Solutions

    Sciencetech, Inc.

    System includes a lamp and monochromator for a tunable light source, which is coupled to a high sensitivity source meter with measurement software. This user-friendly system is the most powerful Spectral Response system currently on the market, but its true power is the ease of upgrading from the base PTS-1 to the more powerful PTS-2-QE (Quantum Efficiency) or PTS-3-CPM (Constant Photocurrent Method). Designed for researchers who have limited budgets but want to start work immediately, this allows the ability to do baseline studies until additional funding for the full QE or CPM system becomes available.

  • Flashlight Solar Simulator

    Optosolar GmbH

    Flashlight Solar Simulators have the advantage of negligible temperature change to the solar cell. For this reason, they are primarily used in cell and module production environments. Also, they are a more budgetary alternative if large cell areas are to be illuminated, because it is easier to have excellent light uniformity on areas of 8 in x 8 in or larger. So, this type of solar simulator is also used for analysis of large area thin film solar cells. But care must be taken, as some materials (e.g. CIGS) have long inherent time constants, so that the pulse length (better: flash plateau) must be chosen accordingly.
