Information

about Current Amplifiers

A range of current amplifiers are available from ultra low noise (0.18 fA/√Hz), high band width (400kHz) and high gain (10E13V/A). Designed with a small modular construction these current amplifiers are ideal for both lab and OEM applications. With many models to choose from, all applications needs can be met, including photodetection with PMTs and photodiodes, spectroscopy, scanning tunneling microscopy, ionisation detectors and capacitative (pyro, piezo) detectors. These modules are small and offer short electrical connections to the detector before the signal-to-noise ratio significantly decreases due to cable capacitance and noise pickup.
