Component Specifications

Definition
The Lens Contact Surface is a critical precision-engineered interface component within optical lens mounting rings, designed to establish and maintain exact physical contact with optical lenses. This surface ensures proper lens seating, alignment stability, and consistent optical performance by providing a controlled mating surface that minimizes stress concentrations and maintains positional accuracy under varying environmental conditions.
Working Principle
Functions as a precision reference plane that physically interfaces with optical lens edges or surfaces, utilizing controlled surface geometry and finish to distribute clamping forces evenly, prevent lens deformation, and maintain optical axis alignment through mechanical constraint and friction management.
Materials
Typically manufactured from corrosion-resistant alloys (e.g., 6061-T6 aluminum, 304/316 stainless steel) or engineered polymers (e.g., PEEK, Ultem) with hardness specifications (e.g., Rockwell B80-B95 for metals) and surface treatments (anodizing, passivation) to enhance durability and reduce wear.
Technical Parameters
  • Hardness Varies by material (e.g., 80-95 HRB for metals)
  • Surface Flatness ≤0.005 mm
  • Angular Alignment ≤0.02°
  • Diameter Tolerance ±0.01 mm
  • Surface Roughness (Ra) 0.4-1.6 μm
  • Thermal Expansion Coefficient Matched to lens material
Standards
ISO 10110, ISO 1101, DIN 3140, DIN 58750
