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.

MTM-20 High Resolution Thickness Controller
The MTM-20 High Resolution Thickness Controller is specifically designed for the Cressington
sputter coater systems and is fully compatible with the 108auto, 108auto/SE, 208HR sputter coater
systems and with the DC-100 sputter supply for the 308R thin film coating system
