The variable-gain, low-noise current amplifier from Femto GmbH can be used with a lock-in amplifier to provide a 1.2-kHz bandwidth at high gain settings. The DLPCA-200 has a switchable 10-Hz low-pass filter to eliminate wideband noise and to produce accurate DC measurements. It also can measure currents of a few femtoamperes up to 10 mA. The amplifier is suitable for use with high-impedance sources such as photodetectors and ionization chambers.
