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.

2-Wavelength, Polarization-Maintaining WDMs
Thorlabs' Fused Polarization Maintaining (PM) Wavelength Division Multiplexers (WDMs) combine two wavelengths of light in PM fiber while maintaining the polarization of the incident light. These WDMs are reversible; they can also be used to split two discrete wavelengths entering the common port into two separate output ports. They are not designed to split the output from a broadband source. PM WDMs are often used for pump / signal applications that incorporate erbium-doped or ytterbium-doped fiber amplifiers. They can be readily customized for a wide variety of applications, enabling rapid design cycles and new project builds. For custom requests, please contact Tech Support.

Pyroelectric and Thermal Testing
The optional Chamber Task measures the Pulse Polarization response and Small Signal Capacitance of a Pyroelectric material that is being heated and/or cooled within a thermal chamber, on a hot chuck or in a furnace. From these measurements the Spontaneous Polarization Pr(q) and the Dielectric Constant er(q) are computed. These are then combined to determine the Electrical Displacement D(q) as a function of the temperature q.
