Keyence OP-87901 Polarized Light Filter – For IV2 Wide-Field Monochrome Vision Sensors

The OP-87901 is a clip-on optical filter used to significantly reduce glare and specular reflection from shiny or metallic surfaces (like machined aluminum, stainless steel, or plastic films). This allows the AI-powered vision sensor to "see" features and defects that would otherwise be washed out by bright light reflections.
