SAW Grade LiNbO3 Crystal

 

LiNbO3 crystal combines low cost, good mechanical and physical properties as well as high optical homogeneity. Therefore, LiNbO3 wedges have been widely used in fiber isolators and circulators.

 

LiNbO3 is also a good acousto-optic crystal and used for surface acoustic wave (SAW) wafer and A-O modulators. Crystro provides acoustic (SAW) grade LiNbO3 crystals in wafers, as-cut boules, finished components and custom fabricated elements.

 

Anhui Crystro participate in the kinds exhibitions every year: Laser World of Photonics Munich, Shanghai, Photonics West in San Francisco, CIOE in Shenzhen, etc.

 

Crystro provides:

  • LiNbO3 wedges used for fiber optical isolators and circulators.
  • Reliable delivery
  • Strict quality control
  • Technical support
  • Very competitive prices
