Mirror Clamping Mechanism for Kinematic Platforms

Product Specifications

Technical details and manufacturing context for Mirror Clamping Mechanism

Definition

The Mirror Clamping Mechanism is a critical component of Mirror Holder/Kinematic Platform systems, designed to provide secure, stable, and repeatable positioning of optical mirrors while minimizing stress-induced deformation. It ensures precise alignment and maintains optical path integrity during operation, vibration, or thermal changes. The mechanism applies mechanical clamping force, often through screws, levers, or spring-loaded elements, to hold the mirror against reference surfaces or kinematic mounts. It incorporates compliance features to accommodate thermal expansion and prevent mirror distortion while maintaining positional accuracy. Typical materials include aluminum alloy, stainless steel, and spring steel. Key parameters include clamping force (50–200 N), mirror diameter range (25–200 mm), positioning repeatability (±0.01 mm), angular resolution (±0.5 arcmin), operating temperature range (-20 to 80 °C), max relative humidity (90%), material (6061-T6 aluminum alloy per ASTM B221), surface treatment (black anodized per MIL-A-8625), weight (0.5–2.5 kg), and footprint (80×80 to 150×150 mm). These values are directory reference ranges and must be confirmed for the specific model and application. The mechanism is used in laboratory and industrial environments where precise optical alignment is required. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement or integration.

Working Principle

The mechanism uses mechanical clamping force, typically generated by screws, levers, or spring-loaded elements, to press the mirror against reference surfaces or kinematic mounts. Compliance elements within the mechanism allow for thermal expansion and prevent stress-induced deformation, ensuring that the mirror remains stable and accurately positioned. The clamping force is adjustable within a specified range to accommodate different mirror sizes and weights. The design ensures repeatable positioning after repeated clamping cycles, maintaining optical path integrity.

Frequently Asked Questions

What is the typical clamping force range?

The directory lists a clamping force range of 50–200 N, but the exact value depends on the mirror size and application. Always confirm with the manufacturer for your specific model.

Can this mechanism handle thermal expansion?

Yes, the mechanism incorporates compliance elements to accommodate thermal expansion, preventing mirror distortion while maintaining positional accuracy. Verify the operating temperature range for your environment.

What materials are used?

Common materials include aluminum alloy, stainless steel, and spring steel. The directory specifies 6061-T6 aluminum alloy per ASTM B221 for the main body, but confirm the exact material for your model.

Is the surface treatment standardized?

The directory lists black anodized finish per MIL-A-8625. This is a reference standard; verify with the supplier that the product meets your requirements.
