Component Specifications

Definition
An optical window is a precision-engineered transparent component integrated into polycarbonate injection molded lens housings to allow controlled light transmission while protecting internal optical elements from environmental contaminants, mechanical damage, and UV degradation. It maintains optical clarity and structural integrity under operational stresses.
Working Principle
Operates by transmitting specific wavelengths of light with minimal distortion, reflection, or absorption while providing a sealed barrier against dust, moisture, and physical impacts. The window's optical properties are engineered to match the housing's refractive index for optimal light coupling.
Materials
Polycarbonate (PC), optical-grade, with UV-stabilized additives; alternatives include PMMA (acrylic) or glass for specialized applications. Surface coatings: anti-reflective (AR), hard coat, or hydrophobic treatments.
Technical Parameters
  • Diameter 10-50 mm (customizable)
  • Flatness λ/4 at 632.8 nm
  • Thickness 1.5-3.0 mm
  • Transmittance >90% at 400-700 nm
  • Surface Quality Scratch-dig 80-50 per MIL-PRF-13830B
  • Operating Temperature -40°C to +120°C
Standards
ISO 10110, ISO 9022, DIN 3140, MIL-PRF-13830B
