Application Areas

AT, BT, SC cut orientations serve frequency control applications in electronics and space technology, including mobile phones and satellites. AT-Cut quartz is the most common configuration, ideal for electronic instruments requiring frequency ranges of 0.5-300MHz. Z-cut quartz supports optical applications such as windows and lenses. Polishing specifications are optimized to reduce electronic resistance or enhance optical transmittance.
