In-Situ Thin Film Thickness / Deposition Rate Monitor with Software, and Optional Sensor, Quartz Crystals - EQ-TM106-LD

In stock
Item Number: TM106-LD
Transported by LTL Freight (Truck)


EQ-TM106-LD is a high precision thickness sensor/monitor for the thin film deposition process. It is based on the principle that the mass of a deposited film on a quartz crystal can be measured by monitoring the change in crystal’s oscillating frequency. If the density of deposited material is known, the thickness can be determined to a high resolution of sub-Angstrom (0.037 Å for this equipment).
