Cryogenic linear stages are specialized versions of SLC stages and completely retain the compact design of the room temperature versions. Therefore, they are ideally suited for limited spaces, typically found in heat shields of cryostats. Materials are selected to match the required thermal properties and prevent mechanical stress during cooling and heating cycles. This ensures long lifetime under cryogenic and ultra-high vacuum conditions.
The cryogenic option is available for many linear stages of the SLC product series. Please note that the following changes apply to the specifications given in the product specification tables.
- Cryo SLC stages are about 60 % heavier because of the use of titanium as a base material compared to the standard aluminum versions of an SLC stage.
- Cryo SLC stages have a lower blocking force value of 2 N and also a lower lift force value of 1 N compared to 3.5 N and 1.5 N of non-cryo versions of SLC stages.
- Due to an application optimized piezo drive the travel range of the cryo SLC-1720 is 6 mm.
