Mirror Holder / Kinematic Platform

Product Specifications

Technical details and manufacturing context for Mirror Holder / Kinematic Platform

Definition

The Mirror Holder/Kinematic Platform is a critical sub-component of the Mirror Mount Assembly designed to provide stable support and precise multi-axis positioning for optical mirrors. It enables fine adjustments in tilt, rotation, and translation to align optical elements with micron-level accuracy in systems such as lasers, telescopes, interferometers, and scientific instrumentation. The platform typically accommodates mirror diameters from 25.4 to 101.6 mm, with a tip-tilt range of ±4 degrees and a resolution of 0.01 degrees, allowing fine angular alignment. Positioning accuracy is ±0.05 mm, ensuring repeatable placement. Load capacity ranges from 5 to 20 kg, depending on the model. Operating temperature is specified for non-condensing environments from -20 to 80 °C. Materials on file include aluminum alloy (6061-T6 per ASTM B221), stainless steel, and Invar, with surface finish typically Ra 0.8 per ISO 1302. Weight varies from 0.5 to 2.5 kg based on size and material. Mounting threads are compatible with standard posts, typically M6 to M12 per ISO 965. The platform uses kinematic principles, typically three-point contact with ball-and-socket or flexure joints, to constrain all six degrees of freedom while minimizing stress and deformation. Adjustment mechanisms, such as screws, piezoelectric actuators, or manual controls, apply controlled forces to precisely reposition the mirror relative to its mounting base. This design ensures stability and repeatability in demanding optical applications. For specific models, verify all parameters and standards with the legal manufacturer or supplier, as values are reference ranges and may vary.

Working Principle

The platform employs kinematic design, typically using three-point contact with ball-and-socket or flexure joints, to constrain all six degrees of freedom without over-constraint. This minimizes stress and deformation, ensuring stable mirror positioning. Adjustment mechanisms, such as fine-pitch screws, piezoelectric actuators, or manual controls, apply controlled forces to tilt, rotate, or translate the mirror relative to its base. The kinematic coupling provides repeatable positioning with micron-level accuracy, as indicated by the positioning accuracy of ±0.05 mm. The tip-tilt resolution of 0.01 degrees allows fine angular adjustments. The design ensures that the mirror remains stable under varying loads up to 20 kg and temperatures from -20 to 80 °C. The use of materials like aluminum alloy, stainless steel, or Invar provides thermal stability and rigidity. The platform's surface finish (Ra 0.8) and mounting threads (M6–M12) ensure compatibility with standard optical posts and mounts.
