a piezo-electric quartz is a quartz crystal capable of vibrating with a very precise frequency(like the crystal used in a quartz watch). This frequency can be modified by applying a mass to one of the surfaces of the quartz. Hence, the thin layer is applied to a quartz crystal, placed in the vacuum chamber with the lenses to be coated. Thanks to electronic processing, the variation in frequency is converted into a precised measurement of the thickness and rate of application of the thin layer.
