High Conductivity SAW Grade Black-LT Wafer For Surface Acoustic Wave(SAW) Devices

High Conductivity SAW Grade Black LT Wafer

Introduction:



Lithium Tantalate is one of the most versatile materials. LiTaO3 has numerous applications including electro-optical modulators, pyroelectric detectors, optical waveguides, SAW substrates, and piezoelectric transducers due to unique electro-optical, pyroelectric, piezoelectric, and acoustic properties, a wide transparency range, and a high optical damage threshold combined with good chemical and mechanical stability.


Advantages:

  • High optical damage threshold
  • Wide transparency range
  • Wide application
