Kinematic Base, Magnetic, 3 inch Square
The BK Series of kinematic bases has magnetically coupled top and bottom plates, providing repeatability of less than 100 μrad. The BK-3A kinematic base has a 3.0 x 3.0 inch top and bottom plates. Kinematic bases allow you to mount, remove, and replace optical components with very high repeatability. 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-3A-T is an extra top plate that may be ordered separately.
Convenient Magnetic Coupling
Bolt Down Anywhere at Any Orientation
The BK-3A kinematic bases feature a freely rotating disk insert with an eccentric clearance slot. Permiting 0.72 in. of translation which covers at least half the diagonal distance of standard 1.0 in. (25 mm) mounting hole grids, this patented mounting method allows an optical component to blot down anywhere and at any orientation on our optical tables and breadboards.
