Inficon STM-2 USB Thin Film Thickness/Rate Deposition Monitor

Overview
A Complete Package Consists of

The STM-2, small in size and price, big in performance. This USB powered thin film monitor comes with everything you need to connect a QCM sensor/feedtrough to a Windows® computer. Allowing up to eight STM-2s monitoring up to eight sensors can be connected to a computer simultaneously.

Features

Most economic QCM monitor
Internal oscillator (no external oscillator or power supply is required)
High accuracy at 10 measurements per second
Compatible with an external oscillator
Size and simplicity make setup & operation easy & efficient

Applications

Research and development
Industrial vacuum coating
Display
Optics
Semiconductor
Solar

Notes:

We do not recommend extending the USB beyond the cable shipped with the STM-2.
Additionally, with the BNC cable, there is a length maximum from oscillator to crystal of 1 m. This includes the BNC from the oscillator to the feedthrough as well as the in-vacuum cable.

A complete STM-2 deposition control system requires four components:

STM-2 Deposition Controller (USB and BNC Cable Included)*
Crystal Sensor
Vacuum Feedthrough
Crystals

*Connected to computer

Note: Below you will find common components needed to build a complete package. If you do not see an item that you need, please contact your local KJLC Sales Representative.

Components Needed	Description
QCM Sensor	The type of necessary sensor is based on the application. For common applications, a Front Load Sensor or Cool Drawer Sensor with a single crystal holder may be appropriate. Please note that the STM-2 does not work with shuttered sensors.
In-Vacuum Cable	The In-vacuum cable is generally supplied with the QCM Sensor. If a replacement is required, please view the Accessories table below.
Feedthrough	Most QCM sensors are available with or without a feedthrough, where coming with a feedthrough is the most common. These feedthroughs come standard with either a 1" bolt or DN40CF flange.
Crystals	Crystals, whether Gold, Silver, or Alloy, are all dependent on the process. Please view the QCM Crystal page for further details.
Short 6" BNC Cable	The short BNC cable connects the atmospheric side of the flange to the oscillator. A 6" BNC Cable is included with the STM-2. If a replacement is required, please view the Accessories table below.
Oscillator	The STM-2 is the active oscillator/monitor in 1 package.
Sensor Input BNC Cable	The sensor input BNC cable connects the other end of the oscillator to the computer via USB. A 5 meter cable is included with the STM-2.
