Lens Body: weight 5-50 g depending on size

Q: What tolerance levels are required for lens body manufacturing?

Lens bodies typically require dimensional tolerances of ±0.005 mm or better, with surface flatness under λ/4 at 632.8 nm wavelength to ensure proper optical alignment and performance.

Q: How does material selection affect lens body performance?

Material selection impacts thermal stability, weight, corrosion resistance, and compatibility with optical elements. Aluminum offers good strength-to-weight ratio, stainless steel provides corrosion resistance, while engineered polymers offer thermal and chemical stability in specific applications.

Q: What standards apply to lens body manufacturing?

Key standards include ISO 10110 for optical elements, ISO 14999 for interferometric testing, DIN 3140 for optical mounting, and DIN 58750 for optical component specifications.

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.
