Crystal thickness monitor

Weboscillating quartz monitor using a single quartz crystal, with two pairs of gold electrodes deposited on it. The possibility of using this arrangement was investigated by Van Empel et al (1971a, b). However, several commercial quartz crystal thickness monitors (Fox and Katz 1969) are also available in which two quartz crystals are used. WebSPECIFICATIONS. SungThai offers both 5 MHz and 6 MHz AT-cut quartz thickness-monitor crystals. These products are offered with gold, silver, and alloy coated electrodes for major optical and vacuum coating applications, PVD, and for use in thin film deposition processes. Silver-aluminum alloy quartz monitor crystalsl is coated with optical film.
