ZAMP / ZPA Preamplifier


Gilden Photonics offers a variety of low noise, high gain amplifiers to work alongside single channel detectors. The amplifier is used to convert detector output signals, and amplify the signals. Signals are then inputted to other measurement equipment, such as Data Acquisition Systems, oscilloscopes, and DMM, to achieve weak signal measurements.

Available models:

  • ZAMP Trans-impedance Amplifier
  • ZAMP is suitable for high impedance detectors.
  • Power supply mode: ZPS-24

Available current mode amplifiers:


  • ZPA-7 for most high shunt resistance (RD>25KΩ) detectors.
  • ZPA-5 for low impedance (RD<400Ω) detectors.
  • Power supply mode: ZPS-PN12
