Product Description
Kinematic bases allow you to mount, remove, and replace optical components with very high repeatability. Three polished steel balls in the bottom plate register with a hardened cone, groove, and flat in the top plate so the two plates relocate precisely every time. These bases are especially timesaving in setups where optical elements must frequently be interchanged, or when reference elements must occasionally be inserted in an optical path. The BK Series of kinematic bases has magnetically coupled top and bottom plates, providing repeatability of less than 100 mrad. BKL Series kinematic bases have mechanically coupled top and bottom plates via a locking thread. Extra top plates are available for all of these kinematic bases.
