Small, for TE cooled detectors
SIP-TO8 series
Transimpedance preamplifier
SIP-TO8 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 thermoelectrically cooled detectors in TO8 package. SIP-TO8 is dedicated for OEM applications and requires external heatsink (MHS-2). 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-2TE, PC-3TE, PC-4TE
Photoconductive optically immersed: PCI-2TE, PCI-3TE, PCI-4TE
