DBR System

We are making a company of trust with a unified heart.
We provide Metal Coating Systems through QCM machine.
QCM measures a mass variation per unit area by measuring the change in frequency of a quartz crystal resonator.
QCM is useful for monitoring the rate of deposition in thin film deposition systems under vacuum.
