Typical Specifications
1. SAW(Surface Acoustic Wave) devices, frequency filters and resonators for wireless communications.
2. IF communication devices because of its stable frequency characteristics in a variable temperature environment.
3. Optical quartz plates are used in multi-refraction applications in digital cameras and videos
4. As a "pick-up" for DVD and optical discs. Future applications for optical plates are in sensors:
I. ITS (Intelligent Transport System)
ii. VICS (Vehicle Information and CommunicationsS ystems)
iii. AHS (Automated Highway systems)
iv. Control devices for optical fiber cable communication.
