AIP series

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.

See specification
