Product Overview
Absolute Optical Contrast
Manufactured using an advanced vacuum photo-etching process, our negative resolution targets feature completely transparent line pairs against a "dead-black" chrome background. This >3.0 OD opacity guarantees the maximum signal-to-noise ratio for machine vision calibration.
Micron-Level Edge Sharpness
Precision is our priority. The microscopic elements—down to Group 7—are fabricated with razor-sharp edges and zero micro-burrs. This ensures your imaging systems and industrial microscopes calculate precise line pairs per millimeter (lp/mm) without reading errors.
Global Compliance & Reliability
Strictly engineered for civilian industrial applications, including semiconductor inspection, automated metrology, and optical instrument calibration. We guarantee reliable, compliant, and unrestricted global supply of high-precision non-controlled optical components.
