High reliability
Well proven design
Field of View
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 .
