Quality Monitoring Crystals

Available in 5 and 6MHz with gold, silver or stress reducing alloy electrodes, our quartz monitoring crystals are produced to stringent specifications and carefully inspected to assure high yields and optimum reliability.

We recommend gold crystals for most applications. They have low contact resistance and high chemical stability. The gold electrodes crystals are best suited for low stress material coating monitoring.

Silver crystals will provide superior performance in processes with high heat loads.

Alloy crystals are recommended for optical coating with dielectric materials and for semiconductor processes with high-stress materials.

Some multi-layer and other specialised thin film applications can be better served by the use of crystals which are tuned to a very narrow frequency band. Similarly, certain controllers are also designed to operate with crystals of a selected frequency band.
