The All-Rounder
Model DLPCA-200

  • Variable gain from 103 to 1011 V/A
  • Detection of sub-pA to 10 mA
  • Bandwidth DC to 500 kHz
  • Rise time down to 700 ns
  • Low noise down to 4 fA/Hz
  • THE all-purpose current amplifier

For Higher Speed
Model DHPCA-100

  • Bandwidth DC up to 200 MHz
  • Rise time down to 1.8 ns
  • Variable gain from 102 to 108 V/A
  • Built-in signal filters for reduced broadband noise

For Highest Sensitivity
Model DDPCA-300

  • Very low noise: min. 0.2 fA/Hz
  • Variable gain from 104 to 1013 V/A
  • > 240 dB dynamic range for sub-fA to
    mA measurements
  • Very low drift < 1 fA
  • Easy to use: convert your standard voltmeter to a high-end sub femto ampere meter

The LUCI-10 amplifier interface allows remote control of FEMTO amplifiers and photoreceivers with a remote control capability from a standard Windows PC with USB port.
