Fixture Body / Base: Weight Capacity 5-50 kg

Component Specifications

Definition

The fixture body/base serves as the foundational structural element in lens holding fixtures, engineered to maintain precise dimensional stability, vibration damping, and thermal consistency during optical component machining, polishing, and inspection operations. It interfaces with positioning mechanisms and clamping systems to ensure sub-micron repeatability in lens alignment.

Working Principle

Provides rigid mechanical support and reference surfaces for lens positioning systems, utilizing kinematic mounting principles to minimize stress-induced deformation while maintaining thermal stability through controlled material expansion coefficients.

Materials

Precision-grade aluminum alloys (e.g., 6061-T6, 7075-T651) or stainless steel (304/316) with stress-relief annealing; surface treatments include hard anodizing (25-50μm) or nickel plating for wear resistance.
