Chamber/Pyroelectric Task
-
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. The Chamber/Pyroelectric Task is quoted upon request.
