Pyroelectric Detectors
Filter Curves (Scans)

Filter Scan Selector

The following table links to pdf files showing the typical transmission curves of InfraTec standard filters for pyroelectric detectors / sensors. 

The exact filter data depend on the requirements of the customer and on the filter production L/N. 
A filter transmission curve is supplied for every InfraTec filter.
