What Are Machine Vision Lights? A Beginner’s Guide with Pro Insights

Why Lighting Is the Secret Weapon of Machine Vision

Most people think machine vision is all about cameras and AI—but in reality, lighting is the unsung hero. Without the right illumination, even the most advanced camera and software can’t “see” what matters.

Machine vision lighting isn’t just about making things brighter. It’s about engineering contrast—highlighting the features you care about (like a scratch, barcode, or missing component) while suppressing everything else. Think of it like using a flashlight at a specific angle to reveal fingerprints on glass: the light creates the information the system needs.
