Small, for uncoold detectors

Transimpedance preamplifier

SIP-TO39 is a series of ultra-small transimpedance, AC or DC coupled preamplifiers. It is designed to operate with either biased or non biased detectors. It is compatible with VIGO thermoelectrically cooled detectors in TO39 package. SIP-TO39 is dedicated for OEM applications and does not require external heatsink. There is a possibility to adjust gain (devices with a frequency bandwidth up to 100 MHz).

Types of VIGO detectors that can be integrated with SIP-TO8 preamplifier

  • Photoconductive: PC
  • Photoconductive optically immersed: PCI
  • Photovoltaic: PV, PVA
  • Photovoltaic optically immersed: PVI, PVIA
  • Photovoltaic multiple junction: PVM
  • Photovoltaic multiple junction optically immersed: PVMI
