Optic Holder / Clamp: Holding Diameter Range 10-100 mm

Q: What is the difference between kinematic and non-kinematic optic holders?

Kinematic holders use precisely defined contact points (3-ball or groove-flat-vee) for deterministic positioning and repeatability, while non-kinematic holders use multiple constraints that can induce stress and reduce alignment accuracy.

Q: How do I prevent optical damage during clamping?

Use compliant interface materials (PTFE, rubber inserts), distribute clamping force evenly, avoid overtightening, and ensure clean, debris-free contact surfaces. Follow manufacturer torque specifications.

Q: What maintenance is required for optic holders?

Regular cleaning of contact surfaces, lubrication of adjustment mechanisms (if specified), inspection for wear or corrosion, and periodic recalibration of alignment features.

Component Specifications

Definition

A specialized mechanical fixture designed to rigidly hold optical components (lenses, mirrors, prisms, filters) while maintaining precise positional and angular alignment within optical systems. It provides adjustable clamping force, vibration damping, and thermal stability for critical optical applications.

Working Principle

Utilizes mechanical clamping mechanisms (screw, lever, or spring-based) to apply controlled pressure on optical elements without inducing stress or distortion. Incorporates kinematic mounting principles for repeatable positioning and alignment through precisely machined interfaces.

Materials

Aluminum alloy (6061-T6, 7075-T6) for lightweight stability, stainless steel (304, 316) for corrosion resistance, or invar for thermal stability. Surface treatments include anodizing (hard coat), passivation, or nickel plating.
