InfraTec uses single crystalline LiTaO3 polished on both sides as pyroelectric material. This permanently polarized material has a Curie temperature of 620 C and therefore does not limit the usable temperature range. The maximum operating temperature of the detector is therefore mainly limited by the parameters of the integrated preamplifiers. The mechanical properties of the built-in IR filters or windows and its assembling technology limit the minimum and maximum storage temperature.
