SThM Module
(Scanning Thermal Module)
VERTISENSE™ SThM MODULE
1. VertiSense SThM is a plug-in module that is compatible with most commercial AFMs
2. It includes:
- Thermal Probe
- Interface Box (Pre-Amplifier)
- SThM Imaging Amplifier
- Wireless Controller (Android Tablet) with VertiSenseApp
3. Interfaced to an AFM system through signal access module (breakout box)
4. Innovative probe design
- Hollow silicon tip integrated with the thermocouple sensor (50 nm) at the apex of the tip
- Thermocouple isolation limits heat loss from the sample during measurement & achieves temperature sensitivity down to 0.01 °C
- Allows imaging by temperature mapping mode (TMM) or conductivity mapping mode (CMM)
by adjusting the position of AFM laser (panel F) on cantilever
- Choice of sensor & cantilever materials allows temp. measurements up to 700 °C without significant bending of cantilever
- Enables Contact/Tapping™/Peak Force Tapping™ modes
- Probes are pre-mounted on adapters specific to AFM systems
5. Interface box (Pre-amp)- Signal conditioning
6. SThM Imaging Amplifier- Ultra-low noise, high speed amplifier for accurate and precise measurements
7. Wireless Controller- Android tablet with VertiSense App to control the amplifier and display Real Time temperature
