71774 Thermopile Detector Preamplifier
The 71774 is a low noise, low drift, battery operated
preamplifier designed specifically for Oriel Thermopile
Detectors (described on page 1244). Use the 71774 to amplify
the voltage from a thermopile detector to a level that can be
measured and displayed by our new Optical Power Meter (see
page 1131), a standard voltmeter, or an A/D card in a computer.
The 71774 has a fixed gain of 1000 amplifying the µV level
signals of typical thermopiles to mV levels.
MINISPECTROMETERS
Two Bandwidths
The 71774 has two bandwidths: DC to 2 Hz and DC to 100 Hz.
Use the DC to 2 Hz output with slow thermopiles or very slowly
varying signals, for the lowest noise performance. The DC to
100 Hz output should only be used for faster responding
thermopiles and signals, since the additional bandwidth carries
the penalty of higher noise levels and more susceptibility to AC
mains frequency interference.

BNC to Female Banana Plug Adapter
The 71774 has BNC input and output connectors. The 70028
Adapter converts the BNC connectors on the 71774 to female
banana plugs, so you can use the preamplifier with your
own detectors.
