Polarity Tester
PT-1
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

CT Polarity Tester
DIR CT
SCOPE proudly introduces Dir CT, a CT Polarity Tester specially designed to verify correctness of polarity of current transformers cores in live EHV switchyards. Polarity test is one of the most common yet crucial tests required to be done on current transformers by commissioning as well as maintenance engineers. Even though it is commonly conducted check, there was no all in one simple tool available for this measurement. DIR CT fills this void to perfection, it is expected to significantly reduce the time taken for polarity checks on numerous CT in sub-station, especially during commissioning of new sub-stations

Integrating Spheres
Artifex Engineering GmbH & Co. KG
We offer integrating spheres made from a special polymer suitable for the wavelength range 250nm – 2.5 µm. For longer wavelengths in the range 700nm – 20 µm, a gold coating on a rough, metallic surface is used. Since lasers in this spectral range are usually also high power, we use solid copper as a thermally conductive substrate material. By choosing the size of the integrating sphere, the overall sensitivity of the system can be adjusted. In addition, the detector is independent of inhomogeneities in power density and polarization. The detector is also independent of the incidence location and angle of the laser radiation.

Probe Antennas
Probe antennas are offered as both standard and custom models with a rectangular waveguide interface. Probe antennas can only support linear polarization. These antennas are often used to measure the gain of other antennas by comparing the signal levels of the probe antenna and antenna under testing. The standard models operate across the full waveguide band and offer 6.5 dB nominal gain and 115 and 60 degrees half power beamwidth at center frequency. The below standard offering covers the frequency range of 8.2 to 170 GHz.

Lens Corrected Antennas
Lens corrected antennas are offered with either a circular or rectangular waveguide interface. While lens corrected antennas with a rectangular waveguide interface can only support linear polarization, models with a circular waveguide interface can support various polarization types including horizontal, vertical, left-handed circular, and right-handed circular polarization for broader applications. These antennas are designed and constructed to offer high efficiency, low side lobes and a rugged mechanical configuration. In general, lens corrected antennas are ideal for achieving gain levels of up to 30 dB with moderate side lobe rejections. Additionally, its dielectric lens provides phase error corrections and serves as a radome to protect from environmental conditions.

High-Dynamics PIMag Linear Stage
V-522 • V-524 • V-528
Physik Instrumente GmbH & Co. KG
Reference-class linear stage. Linear positioning stages with magnetic direct drives largely dispense with mechanical components in the drivetrain and the drive force acts directly on the motion platform. Together with precision bearings, a high travel accuracy and longer lifetime is achieved. The linear positioning stages are particularly suitable for scanning applications. PIMag® Voice Coil. Voice coil drives consist of 2 essential components: A permanent magnet and a coil, which is located in the air gap of the magnetic field. When current flows through the coil, it moves in the magnetic field of the permanent magnet. The direction of motion depends on the polarity. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications, which require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.

POLARIZATION CAMERAS
Conventional high-speed cameras have been utilized for nearly eighty years and are widely accepted worldwide through continuous technological development to visualize fast occurring phenomena. In recent years, demand for using polarization in structural dynamics and high-speed object detection has been increased due to the advancement of robotics, clear film production and new materials testing technologies. On the other hand, traditional high-speed cameras lack any polarization sensitivity.

Automatic Bias Controller
MATRIQ-IQABC
Optimizing DC bias points of an IQ modulator is no trivial task. There are six different Mach-Zehnder structures inside one dual polarization IQ modulator, all simultaneously influencing the properties of a single optical signal. Trying to optimize bias points using just the intensity measurement of the optical signal is time consuming, inaccurate and it requires a lot of knowledge and experience.

Beam Directing and Reflecting Optics
Beam directing and reflecting optics simply reflect, bend or translate the beam, but do not typically modify the polarization, except for polarizing beam splitters. For example, mirrors, cube corners and retroreflectors are attached to objects that move in order to keep the weight down on the moving object (instead of mounting the interferometer on the moving object).

Audio Fiber Tracer
CFT-810
Motorized Polarization Controller. In addition to its basic function of adjusting polarization states in multi channels, it also provides convenient ‘save and recall’ functions. As a Scanning PC, it provides very powerful ‘auto scan’ modes with variable scanning speeds. Polarization states can be manipulated by either manual adjustment or remote control (GPIB, RS-232) using two quarter-wave plates in each channel of the PC1600. Additionally, the auto scan mode of FIBERPRO’s Motorized Polarization Controller has been upgraded in LPC, and it shows another auto scan mode of four quarter-waveplates with higher polarization extinction ratio when connecting two channels at a high speed. PC1600 is an essential tool to complete fiber-optic, multi-channel measurement systems such as WDM/DWDM as well as R&D (i.e. PMD experiments), and manufacturing.

Scanning Electrochemical Microscope
VS-SECM (DC And AC)
The SECM integrates a positioning system, a bipotentiostat, and an ultramicroelectrode probe or tip. The positioning system moves the probe close to the surface of the sample, within the local imaging zone. The bipotentiostat can polarize the probe only (feedback mode) or the sample and the probe independently (generator-collector mode), while measuring the resulting current(s). The probe is specially designed to have a specific tapered polish (per the RG ratio) and active radius below 100 microns. The positioning system scans the probe and charts position with measured electrochemical parameters, creating a data map of local current.
