Transimpedance preamplifier

AIP is a new generation of transimpedance, AC or DC coupled preamplifiers. It is designed to operate with either biased or non-biased VIGO detectors. AIP is „all‑in-one” device – a preamplifier is integrated with a fan and a thermoelectric cooler controller in a compact housing. It is very convenient and user‑friendly device, thus can be easily used in a variety of applications.

Types of VIGO detectors that can be integrated with AIP preamplifier

  • Photoconductive: PC-2TE, PC-3TE, PC-4TE
  • Photoconductive optically immersed: PCI-2TE, PCI-3TE, PCI-4TE
  • Photovoltaic: PV-2TE, PVA-2TE, PV-3TE, PV-4TE
  • Photovoltaic optically immersed: PVI-2TE, PVIA-2TE, PVI-3TE, PVI-4TE
  • Photovoltaic multiple junction: PVM-2TE
  • Photovoltaic multiple junction optically immersed: PVMI-2TE, PVMI-3TE, PVMI-4TE
