Pyroelectric Infrared Detectors
Dual Element Detectors LHi 954 / 958
TO-39 / TO-5 housing
High reliability
Well proven design
The
LHi 954
and
LHi 958
pyroelectric infrared-detectors have been a world
standard for more than 10 years. They both are dual element types with FET in
source follower connection. The
LHi 954
detector is available in
TO-39
housing
with standard infrared filter whereas the
LHi 958
is the same detector in a
TO-5
housing with standard infrared filter.
It offers a highly stable responsivity with excellent common mode performance
(match) and low noise .
