Product Overview
Extreme Optical Contrast
Utilizing advanced vacuum photo-etching technology, our chrome patterns achieve absolute "dead-black" opacity against crystal-clear glass. This delivers a pristine, high-signal-to-noise ratio crucial for precise optical sensors and automated inspection.
Micron-Level Edge Precision
Our manufacturing process guarantees razor-sharp grating edges free of micro-burrs, producing clear diffraction signals. This ensures zero-error pulse counting even in ultra-high-speed rotational environments like servo motors and robotics.
Rigorous Quality & Civil-Use Compliance
Engineered strictly for civilian industrial applications such as machine vision and metrology instruments. Every disk undergoes strict optical inspection to guarantee dimensional accuracy, providing reliable, unrestricted supply of non-controlled optical components.
