Quartz crystal microbalances—or QCMs as they are commonly called—are electronic devices used within vacuum deposition chambers to measure thin film thickness on substrates.
6 MHz Quartz crystal sensor. Also called a double-anchor pattern, these crystals are for use in thin film deposition monitors and controllers, including Inficon, Maxtek, Sigma Instruments, and Sycon instruments. AT-CUT, 14 mm diameter.
