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.
