The BK Series of kinematic bases has magnetically coupled top and bottom plates, providing repeatability of less than 100 μrad. The M-BK-2A kinematic base has a 50.8 x 62.23 mm top and bottom plates. 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 M-BK-2A-T is an extra top plate that may be ordered separately.

运动基地的BK系列磁耦合的顶板和底板,提供不到100μrad的可重复性。M-BK-2A运动基座上底板宽50.8 x 62.23 mm。运动学基础允许你安装，删除，和替换光学元件具有很高的重复性。三个抛光钢珠在底板寄存器与一个硬化锥，槽，平坦在顶板，所以两个板精确地重新移动每次。当光学元件必须经常交换，或者参考元件必须偶尔插入光路时，这些基尤其节省时间。M-BK-2A-T是一个额外的顶板，可以单独订购。
