QCM Thickness Monitor



Colnatec is an USA-based manufacturing and has been providing real-time thin film thickness measurement instrument and accessories for years. These products include quartz crystals (AT-type, RC-type and SC-type. All cystrals come with different electrode coating materials for different applications), sensor heads (single-crystal / multi-crystal) and thickness monitor / controller. Colnatec is the first company that takes crystal temperature into account for accurate thickness measurement. Take AT-cut crystal for example, as crystal temperature goes beyond 25°C without proper cooling, the frequency changes becomes nonlinear, causing errors in thickness measurement. Colnatec has developed solutions by incorporating temperature-measuring mechanism to the sensor head, specailly-cut crystals for high temperature applications and special algorithm in thickness monitor  /controller.
