1 kW and 2 kW Laser-Based Floating Zone Furnace
Laser Furnace
The 1 kW and 2 kW laser furnace for single crystal fabrication is based on a design and developed in close cooperation with the RIKEN Center for Emergent Matter Science under the leadership of Yoshio Kaneko. Both melting zones have 5 lasers each, which guarantees a high uniformity of power density in the melting zone range. The laser profile has been optimized to reduce thermal stress during the crystal growth process. In addition, the system includes an integrated temperature sensor for real-time temperature monitoring. Temperatures up to 3000 °C can be reached and therefore materials with a very high vapor pressure, a narrow temperature range of the melt, a high thermal conductivity coefficient and incongruent melts can be melted.

Atomic Force Microscope for SEM/FIB
AFSEM® AFM Insert
AFSEM is an atomic force microscope (AFM), designed for integration in a SEM or Dualbeam (SEM/FIB) microscope. Its open access design allows you to simultaneously operate SEM and AFM inside the SEM vacuum chamber. The correlated image data of AFM and SEM enable unique characterization of your sample, and the combination of complementary techniques is a key success factor for gaining new insights into the micro and nano worlds. AFSEM enables you to easily combine two of the most powerful analysis techniques to greatly extend your correlative microscopy and analysis possibilities.

7 Tesla Optical Cryostat
OptiCool®
The OptiCool by Quantum Design is a new optical cryostat using an innovative design that puts the sample volume in the heart of your optical environment. A custom 3.8 inch bore, split-coil, conical magnet offers fields perpendicular to the optical table up to ±7 tesla. The highly integrated design means, even with a magnet, your sample isn’t buried inside a large cryostat, far away from the optics. Seven side optical ports and one top optical port allow for optical access to your sample from a wide array of directions.
