Low Temperature Optical Cryostat

The low-temperature optical cryostat cools samples to specific low temperatures using refrigerants or thermoelectric cooling, and is equipped with optical windows to allow light transmission. It is used to observe changes in the optical properties of materials in low-temperature environments, commonly applied in low-temperature stability testing of coatings and plastics.
Selection
When selecting, it is essential to match the target temperature range and temperature control accuracy, consider the sample chamber size and compatibility with optical windows, confirm the cooling method (closed-cycle or liquid nitrogen) and vibration control, and evaluate the system’s expandability in conjunction with the experimental requirements for light sources and detectors.
