Variable Temperature UHV SPM

The VT bolt-on-chamber allows the use of an evaporator (EFM 3 VT) during imaging.

More than 300 instruments have been delivered and successfully installed around the world since the first delivery of the original VT STMs in 1994 and the first VT AFMs in 1999. The volume of our customer’s research results and publications is final proof of the unbeatable performance, quality and versatility of the Variable Temperature design.
Up to two EFM 3 evaporators can be directly mounted on the VT chamber for in-situ growth, even during imaging, if the tip geometry permits.
The proven Omicron eddy current damping allows high-resolution SPM even in non-ideal conditions. Every instrument is capable of high performance STM and is available with either beam deflection AFM or "Needle Sensor" AFM.
With the integration of the new IVC H3 preamplifier, the VT AFM and VT STM have further raised the performance and versatility benchmarks for ultra-high vacuum (UHV) STM and AFM.

Optimum STM and STS performance is guaranteed in both the VT STM and VT AFM.

The fundamental difference between the two instruments is in their AFM capacity.
