Transimpedance preamplifier

MIP is a series of medium-size transimpedance, DC or AC coupled preamplifiers, intendend to operate with either biased or non-biased VIGO detectors. MIP is equipped with a fan and does not require any additional external heatsink. It is one of the most user-friendly preamplifier which surely facilitate work.

Types of VIGO detectors that can be integrated with MIP 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
