100um Thick Ultra Thin LiTaO3 Wafer Z Cut For Pyroelectric Applications

100um Thick Ultra-Thin LiTaO3 Z-Cut For Pyroelectric Applications

For many years the pyroelectric material lithium tantalate (LiTaO3 ) has proved itself at use in pyroelectric detectors. It fulfils not only the demands on material characteristic quantities just mentioned but also stands out due to an excellent temperature stability and very good reproducibility of the detector performance.

Typical material properties of LiTaO3 at room temperature are:
p = 1,8 . 10-8 Ccm-2K-1
εr = 43
tanδ = 0,001
cP´ = 3,2 Jcm-3K-1
