Product Description

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

Transparency Range	High transmittance from 0.4 to 4um
Crystal Symmetry	Trigonal, space group C3v OR 3m
Density	7.45
Curie Temperature	605±2℃
Mohs Hardness	5.5
Thermal Expansion Coefficient	αa=16.1×10^-6/k, αc=4.1×10^-6/k
Refractive Indices, Birefringence	n0=2.176, ne=2.18, Δn=0.004 at 0.63um
Dielectric Constants (Relative)	ετ11=53.6; ετ33=43.4
Pyroelectric Coeff. @27℃	0.019 u Coulomb/cm2/℃
Electro-Optic Coeff. @0.63um	Γ13=7×10^-12m/v Γ33=30×10^-12m/v Γ42=20×10^-12m/v
Nonlinear Optical Coeff. @1.06um	d22=2.08×10^-12m/v d31=1.28×10^-12m/v d33=19.39×10^-12m/v
