Dielectric Loss Tangent Testing Instruments
Insulation materials in electrical equipment are used between a pair of electrodes; therefore it can be expressed as capacitors. Applying AC voltage to a capacitor with insulation materials causes an energy loss due to the leak current, the dielectric polarization, and the partial discharge. Because of this, the phase of the capacitor current is more delayed than that of a zero-loss current (reactive current) flowing in an ideal insulation material. The delay angle is called "Dielectric Loss Angle", and the tangent is "Dielectric Loss Tangent" (tanδ). Please refer to the technical guide explained in detail.

Cross Hole Energizer P/S
CHE
Specially designed for small-scale cross-hole surveys, this compact hammer can be used to generate both P and S waves.The hammer can be downloaded using the steel cable and clamped to the requested depth by a pneumatic clamping system manually controlled by a lever from the surface; simply pushing up the steel cable to execute the first shot, the trigger installed on the energizer will start the acquisition for the “P/S”. After that you will have to drop the mass to make the acquisition with inverse polarity.

Dual Polarized Antennas
Dual polarized horn antennas are offered as both standard and custom models with rectangular waveguide interfaces for both horizontal and vertical ports. These dual polarized horn antennas support both linear and elliptical polarized waveforms. When the antenna receives a circular polarized waveform, equal amplitude linear polarized waveforms are output at both horizontal and vertical ports. When two equal amplitude linear polarized waveforms are input into the vertical and horizontal ports, the antenna will transmit a circular polarized waveform. The listed models offer 15 dB nominal gain and 33/28 degrees typical half power beamwidth at the center frequency of the band. They also exhibit 40 dB typical port isolation and 35 dB nominal cross polarization. These antennas cover full waveguide bandwidths within the frequency range of 8.2 to 110 GHz. In addition to the models listed below, models with 10, 20, 23 and 25 dB gain and other frequency bands are also available.

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.
