Universal SPM Head: Compact, Rigid and Stable
- Rigid design with small footprint
- STM, AFM & spectroscopy
- Compatible with low temperatures down to mK range
- Entirely non-magnetic design
- Orthogonal 3D coarse motion
- Independent tip and sample exchange
- Easy handling
The ultra-compact TRIBUS is a universal SPM for a wide variety of applications. Whether for SPM-spectroscopy, surface imaging, or manipulation of nanoparticles, for experiments at elevated temperatures or at the milli-Kelvin scale, in high magnetic fields or in spatially tight environments, the TRIBUS SPM is the ideal choice whenever highest resolution, accuracy and flexibility are required.
The TRIBUS SPM head was designed for high resolution STM, QPlus®-AFM, and spectroscopy experiments in a temperature range between mK and up to 420 K.
Due to its small footprint, non-magnetic materials, and compatibility with a wide temperature range the integration into almost every UHV environment is possible.
Special attention was paid to the selection and pre-characterisation of materials for the TRIBUS head. As a result, it has a minimal thermal drift and optimum stiff ness, which yields excellent stability in the SPM.
Aspects such as 3D coarse motors with independent and orthogonal axes, and easy and safe in-situ tip and sample exchange, facilitate ease of daily work. Additional features such as multiple electrical sample contacts and optical access ports extend the possible applications beyond standard SPM measurements.
There are two variants of the TRIBUS: TRIBUS Ultra for temperatures down to mK range and high magnetic ﬁelds (> 2T), and TRIBUS for temperatures above 1.1 K and magnetic ﬁelds of < 2T.

Multiple Sample Contacts
In addition to the standard sample contact, the sample acceptor stage carries up to 10 electrical contacts
Two variants of the TRIBUS SPM head can be offered. Both variants have the same design and dimensions and only differ in the head-material and temperature sensors:
- Temperature range: >1.1 K to 420 K
- Magnetic field compatibility: B <2T
- Temperature sensor: Si-diode
- Temperature range: mK to 420 K
- Magnetic field compatibility: tested to BZ=12T
- STM-measurements in dynamic and static magnetic field possible
- Temperature sensor: Cernox
Different adapters for integration in custom systems available.
