Quartz Sensor Crystals |
|
BeamTec offers an extensive line of quartz sensor crystals which cover a wide array of crystal microbalance measurement applications. Applications range from thin film deposition in vacuum to metal plating in liquid to various crystal microbalance research applications where measurement accuracy is critical. BeamTec stocks replacement quartz crystals for most commercially available film thickness monitors. These include 6 MHz, 14mm diameter crystals (for Inficon, Sycon, Sigma Instruments and Maxtek instruments), 5 MHz, 14mm diameter crystals (for Balzers instruments), 5 MHz, 12.5mm diameter crystals (for Ulvac and Sloan instruments), and the new 8mm diameter 5 or 6 MHz crystals for Colnatecs revolutionary 24-crystal sensor head, Infnity™. We offer the standard electrode coatings as well: gold/chromium, silver/chromium and aluminum (or "alloy"). We also offer the unique RC™ cut quartz in standard frequencies and geometries. The RC™ does not respond to thermal radiation as a typical AT-cut crystal does, leading to the highest accuracy quartz film thickness crystal ever made! |
