Field of View
Two seperate elements, size 1,5x1,5
Individual spectral window for each element
Designed for Gas Analysis applications
The LHi 814 pyroelectric infrared-detector series is specially designed for gas
analysis and monitorring applications. It includes two pyroelectric elements,
each having a FET in source follower connection.Thus two outputs are given.
The detector is encapsulated into TO-5 housing with two seperated spectral
narrow band infrared windows.There are many filters available for the selected
spectral bandwidths. Often one channel is used as reference channel.
