Kinematic Base, Locking, 88.9 x 101.6 mm, Metric

The M-BKL-4 kinematic base has a mechanically coupled 88.9 x 101.6 mm top and bottom plates via a locking thread. 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 M-BKL-4-T is an extra top plate that may be ordered separately.

Reliable Mechanical Coupling

BKL-4 Locking Kinematic Base

The BKL-4 Kinematic Bases are designed with a threaded lock-down mechanism located in the center of the base plate. Turning the thumb-wheel in the base plate rotates a threaded post, which tightens the tapped top plate to the base. Because the lock-down mechanism is located in the center of the three kinematic reference points, locking pressure is applied gradually and evenly for repeatable positioning time after time.
