Polarization Technology
Polarization refers to the orientation of light waves in a specific direction. In unpolarized light, waves vibrate in multiple planes. A polarizer filters this light, allowing only waves aligned in a particular direction to pass through. In machine vision, this principle is used to reduce glare, enhance contrast, and reveal surface details that would otherwise be obscured by reflections.
Effilux offers a wide range of polarizing accessories and integrated solutions adapted for both visible and near-infrared (NIR) applications.
Why Polarization Matters in Machine Vision Lighting
Lighting plays a crucial role in the effectiveness of polarization. When used correctly, polarized lighting can:
- Eliminate glare: Suppress reflections from shiny or transparent surfaces (e.g., plastic, glass, metal)
- Enhance contrast: Reveal surface defects, textures, or markings that would otherwise be hidden
- Enable backlight analysis: Highlight solder joints, holes, or thickness variations in transparent materials
Industrial Applications of Polarized Lighting
Effilux polarization solutions are ideal for:
- Inspection through transparent packaging: Detect defects or labels inside plastic bags or containers
- Surface inspection: Identify scratches, residues, or coating inconsistencies on reflective materials such as metal parts
- Assembly verification: Confirm presence and alignment of components with reduced glare
