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.

Piezoelectric Testing
-
Radiant Technologies, Inc. specializes in the measurement of electrical and piezoelectric properties of non-linear materials. The Piezoelectric Task captures a sample's displacement as a function of voltage profile along with the sample's polarization response. An external displacement measurement instrument must be attached to a Radiant Precision Test System to make this measurement. All of the Radiant testers are equipped with a high-impedance voltage input to capture the output of a displacement sensor. Every Vision measurement task will collect data from that sensor input simultaneously with the measurement being executed. Radiant's test systems work easily with displacement sensors which include:

Spectroscopic Ellipsometer
SE Series
-
Angstrom Sun Technologies, Inc.
Spectroscopic Ellipsometer SE series are advanced models built by Angstrom Sun Technologies Inc. Ellipsometry is a technique utilizing polarization state changes after light beam reacts with probing samples. A typical ellipsometer setup includes a light source, polarizing optics (like polarizer, analyzer, phase retarder or called as compensator), sample stage, detecting unit, incident angle change mechanism, computer and software for data acquisition and modeling. Not like reflectometer, ellipsometer parameters (Psi and Del) are always obtained at non normal incident angles. By varying incident angle. many more data sets can be obtained which will be helpful in refining model, reducing uncertainty and improving user's confidence on model's output. Therefore, variable angle ellipsometer is far more powerful than fixed angle ellipsometers. Furthermore, by utilizing broadband light source, spectroscopic data over a wavelength range with many wavelength points can be obtained and thus measurement precision and accuracy for optical properties can be greatly improved. The measurement speed for spectroscopic data has been overcome by implementing an advanced detector array so thousands of data can be acquired simultaneously. With such configuration and capable of collecting more data sets, the complicated layer stacks could be analyzed with powerful functions built within software.

G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation

Radiant's Chamber/Pyroelectric Task sets the sample to a series of temperatures by performingGPIB control of an external thermal device. At each temperature it captures the sample’s polarization response and/or small-signalcapacitance. These are combined to calculate the pyroelectric coefficient. The Pyroelectric Task is to be used with a Radiant Test System and a Linkam Stage (-196C to 600C), Thermal Chambers, Hot Chucks, or a Furnace to automatically measure the Pulse Polarization response and Small Signal Capacitance of a Pyroelectric material that is being heated and/or cooled. Radiant's Pyroelectric measurement Task can be added to Vision at additional cost. This measurement suite fully characterizes the pyroelectric charge (polarization) response of the sample under test. The Pyroelectric Task suite controls various thermal controllers such as Quantum Design, Lake Shore, Delta Design, and many others. Detailed Listing of Thermal Controllers Registered in Vision.

Flame Ionization Detector
-
A flame ionization detector converts a hydrocarbon gas concentration into an electrical signal. The flame is hydrogen fueled and burns in hydrocarbon free combustion air. Either side of the flame are two electrodes between which an electric field is generated by means of a polarization voltage. The sample is pre-mixed with the fuel gas and heated in the flame to a temperature at which the hydrocarbon molecules ‘crack’ and CH fragments appear. These CH fragments are oxidated by the oxygen in the combustion air resulting in the formation of CHO+ ions. The ion current then passes to the electrodes and the resulting current measured is proportional to the quantity of C atoms derived from organic compounds.The Thermo-FID features two separate microprocessor controlled pressure compensations to avoid any influence from environmental or sample conditions. In addition, the complete Thermo-FID range of analyzers are equipped with a flame trap that is used as a heated sample inlet filter. The measurement chamber and all material in contact with the sample gas are heated between 120°C and 200°C to avoid condensation.
