Product Overview
Ultimate "Dead-Black" Contrast
Coated with high-density vacuum chrome on a pure, transparent glass base. When paired with backlight illumination, the target delivers extreme signal-to-noise ratios, completely eliminating reflections and ghosting for flawless edge detection.
±5μm Edge Sharpness
Manufactured utilizing advanced optical photolithography. The critical cross-junctions of our checkerboard pattern are flawlessly sharp and free of micro-burrs, ensuring absolute sub-pixel accuracy for your system algorithms.
Compliant B2B Global Supply
Strictly engineered for civilian industrial applications such as robotics, 3D scanning, and AOI inspection. We provide reliable global export and technical sourcing support for international machine vision integrators.
