Monitor quartz crystals are precision AT-cut quartz resonators used in Quartz Crystal Microbalance (QCM) systems to measure thin-film growth during vacuum deposition. As material is deposited onto the crystal surface, its resonant frequency changes proportionally to the mass of the deposited film. This enables real-time monitoring of deposition rate and total film thickness with exceptional accuracy, helping researchers and manufacturers maintain precise process control throughout the coating cycle.
A monitor quartz crystal is mounted inside the deposition chamber where it experiences the same coating environment as the production substrate. The QCM controller measures tiny frequency shifts as material accumulates on the crystal. Using the Sauerbrey equation, the instrument converts these frequency changes into deposited mass and film thickness, allowing operators to start, adjust, or stop the deposition process at the desired thickness.
UniversityWafer supplies monitor quartz crystals in industry-standard 5 MHz and 6 MHz frequencies with gold, silver, alloy, or blank electrode configurations. Available in common diameters such as 12.45 mm and 13.97 mm, these precision crystals provide excellent frequency stability, repeatability, and compatibility with many commercial QCM monitoring systems used in research and production environments.
