The linear cryogenic stages are specialized versions of SLC Series stages. They completely retain the compact design of the room temperature versions and are therefore ideally suited for limited spaces typically found in heat shields of cryostats. We use titanium for the base of the stages and solid-state coating as dry lubricants for our high precision bearings. Materials are selected to match the thermal properties to prevent mechanical stress during cooling and heating cycles. This ensures long lifetime in 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-1722 is 6 mm.
The SLC-2430 is the smallest stage of the SLC-24 series. It was designed to meet highest accuracy under more rigid conditions. It offers a travel range of 16 mm and is able to handle normal loads of 20 N.
The nanometer precision liner stages SLC-2460 offers high straightness for allowing an excellent positioning accuracy. It has a travel range of 35 mm and a normal load of 30 N. Its dimensions are 60 x 24 x 10.5 mm³
