Component Specifications

Definition
The lens body is a critical mechanical component in micro-lens array systems that provides structural support, precise alignment, and thermal stability for individual lens elements. It maintains optical axis consistency, minimizes aberrations, and ensures proper focal length maintenance across the array. Typically manufactured with micron-level precision, it interfaces with mounting systems while protecting delicate optical surfaces from environmental factors and mechanical stress.
Working Principle
The lens body operates by providing a rigid, dimensionally stable framework that maintains precise spatial relationships between optical elements. It ensures consistent optical paths by controlling lens positioning within tolerances typically under 5 microns, while managing thermal expansion coefficients to maintain alignment across operating temperatures. The body's mechanical design incorporates mounting features that allow for precise adjustment and secure attachment within optical assemblies.
Materials
Typically aluminum alloys (6061-T6, 7075-T6) for lightweight stability, stainless steel (304, 316) for corrosion resistance, or engineered polymers (PEEK, Ultem) for thermal/chemical applications. Optical-grade ceramics may be used for extreme thermal stability. Surface finishes include anodizing (Al), passivation (SS), or specialized coatings for optical compatibility.
