Compact sub-Kelvin cryostat with free-beam optical access

S-Type Optical

Integrated. Compact. Reliable.

The S-Type Optical Model 2022 is a fully integrated 19” rack mounted optical cryogenic platform for the continuous, cryogen-free cooling of optical experiments. The cryostat is designed for a broad range of low-temperature experiments and applications that require simple and fast access to the sample stage. The system offers a unique combination of sub-Kelvin temperatures, automatic operation, and free-beam optical access on a small footprint.

Optical Measurements at sub-Kelvin Temperatures

The S-Type Optical offers a unique combination of cryogen-free sub-Kelvin cooling and free-beam optical access on an extremely compact footprint. Additionally, vibration isolation and a sample magnet make it the ideal platform for optical quantum technologies and material science.

Simple Sample Access

The ergonomic design of our optical cryostat results in a small 19″ rack footprint with an easy access to the sample. Additionally, kiutra’s proprietary cryogenic interface allows for 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.
