Scryo-S-500 Microscope Cryostat

The Scryo^®S-500 (abbreviated as S-500) is a new high-efficiency continuous-flow open-loop microscope cryostat with rugged adiabatic support structure and temperature drift compensation design, vibration level in the nanometer scale, is the ideal cryogenic platform for single-quantum-dot, single-molecule, and low-dimensional material testing. The short working distance combined with coaxial inlet and outlet piping allows for use with most commercial microscopes and Raman spectrometers. High-efficiency vaporizer combined with super-adiabatic transfer piping greatly improves the efficiency of liquid helium usage. The cryostat features fast cooling speed, a wide temperature range (<1.8K-420K), a low liquid helium consumption rate and good temperature stability.

The S-500 microscope cryostat comes standard with a fused silica window, optional window materials for transmitting different wavelengths, and a wide range of vacuum electric feedthroughs and electrical leads, with options such as a large sample space model (for integrating nanopositioning stages, objective lenses, and Diamond Anvil Cell, etc.), a structure with vertical extensions (to match superconducting magnets or electromagnets), a stainless steel vacuum shroud, and indium sealing flanges.

The S-500 cryostat is combined with a Helium Cycle Cryogenic System (Qcryo^®) to form a dry, closed-loop cryogenic system (Qcryo-S-500) that does not consume liquid helium, with a minimum temperature of<2.5K and optionally <1.8K, and maintains the ultra-low vibration and drift characteristics of the open-loop mode of operation, with a temperature stability of: ±2.5mK@10min near the minimum temperature.

Typical Cooling Curve of Qcryo-S-500 Dry Cryogenic System

The figure below shows the time-domain vibration displacement and FFT-transformed frequency spectrum in the X-direction of the Qcryo-S-500 dry cryostat. The vibration level (peak-to-peak value) in the X-direction is <4 nm, and the maximum amplitude in the FFT-transformed frequency spectrum (0–1000 Hz) is <0.4 nm.

The figure below shows the time-domain vibration displacement and FFT-transformed frequency spectrum in the Y-direction of the Qcryo-S-500 dry cryostat. The vibration level (peak-to-peak value) in the Y-direction is <4 nm, and the maximum amplitude in the FFT-transformed frequency spectrum (0–1000 Hz) is <0.6 nm.
