S-Type Optical Cryostat Front

The S-Type Optical is a versatile optical cryostat featuring an experimental environment with ultra-low vibrations

The combination of two ADR units provides continuous, cryogen-free sub-Kelvin cooling, independent of helium-3 supply. 

The cryostat and all control equipment fit in a single rack, which makes it a very compact system that can be used in practically any setting. 

With free-beam access, vibration isolation, and a sample magnet, the S-Type Optical is an ideal platform for research in optical quantum technologies and material science. 
The ergonomic design gives you easy access to the sample.

Additionally, kiutra’s proprietary cryogenic interface allows simple integration of experiments that can be prepared outside the cryostat. 

Typical Applications

Innovative cooling for state-of-the-art science and technology

Optical investigation of electronic correlations

The investigation of many-particle correlations, their impact on the bulk properties and transport behavior of condensed matter, and how these correlations trigger the emergence of new and exotic phases is a particularly exciting and active field of research. Several measurements including Rayleigh (elastic), Raman (inelastic), or resonant inelastic light scattering can be used to study collective excitations of the solid state. For such investigations, typically low temperatures in combination with fiber-coupled or free-beam optical access are needed. These requirements are met by kiutra’s S-Type Optical, which offers a unique combination of sub-Kelvin temperatures, free-beam optical access, small working distance, and compact system size to enable various optical measurements.

Low-temperature photoluminescence

The investigation of photo-physical properties yields insights into electronic correlations of lower-dimensional systems or heterostructures. A well-established spectroscopic technique is the observation of photoluminescence, i.e., the analysis of light that is emitted from a sample after the absorption of photons. Tracking characteristic features in the photoluminescence spectra over a broad temperature range provides additional information on the energy scales and correlations of the electronic structure.
