A practical guide to kinematic mount design for custom, real world applications: from theory, to design and analysis, to CAD modeling, to production.

The Principle of Kinematic Constraint

The Principle of Kinematic Constraint

The advantage of a kinematic mount is that it locates one rigid body relative to another with very high repeatability, without over-constraining the body or introducing instability. It accomplishes this by using the precise number (and arrangement) of contact points needed to allow the desired degrees of freedom – no more and no less. That is the principle of kinematic constraint, which this article will show how to apply in your designs.

Split clamp design and analysis

Split clamp design and analysis

Split clamps are a simple, robust method for securing cylindrical components that need to be adjusted axially (e.g., focusing a lens) or rotationally (e.g., a prism holder or an adjustment screw). In both of these cases, the split clamp satisfies one of the principles of a good locking mechanism:

A locking mechanism’s action should not influence the sensitive adjustment that it is intended to secure.
