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