MTM-10 High Resolution Film Thickness Monitor
and MTM-20 High Resolution Film Thickness Controller


film thickness monitor

The High Resolution Thickness Monitor / Thickness Controller are based on the principle that the oscillating frequency of a quartz crystal is changed by the mass of a deposited film on its upper face. Electronically measuring this effect allows for a determination of the thickness of a deposited film. Once the density of the evaporated material is entered into the system, the thickness is measured to a resolution of 0.5nm on a four digit LED display having a range of 0-999.9 nanometers. The crystal and holder are mounted in the vacuum chamber and connected to the FTM Power Supply via the supplied vacuum feedthrough.

System Consists of:
  • MTM-10 Controller Box
  • BNC Cables / BNC Elbow
  • Oscillator Box
  • CS-108 Vacuum Feedthrough with BNC/SMB Connector and Integrated O-ring Seal
  • Crystal Head Cable 7" / 108mm
  • Crystal Monitor Head with M4 bracket screw size ø18 x 21mm height. Crystal area 6mm
The MTM-10 High Resolution Thickness Monitor will fit any of the Cressington sputter and carbon coating systems as well as other thin film vacuum coating systems which allow for a vacuum feedthrough of 10 mm diameter a on a plate thickness of 9 mm.

MTM-10 High Resolution Thickness Monitor

the economical way to assure thickness control

Accurate manual control of film thicknesses during deposition is difficult if not impossible. A white tile with a drop of oil is sometimes used for rough estimates of coating thicknesses of carbon but cannot be used when repetitious, reproducible coatings are required. Using instrumental settings is also not an accurate method because vacuum level (for sputtering) and time (for evaporation) are very critical parameters. The High Resolution Thickness Monitor offers repeatability of coating thicknesses, removes guesswork and is convenient. The use of a tooling factor allows for exact measurement of the thin films. The MTM-10 High Resolution Thickness Monitor works with many types of vacuum thin film coating equipment.
