Mercury™ II Series Glass Scale
Superior resolution, seamless integration.
The Foundation of Accuracy
Designed as the perfect partner to our Optical Encoders, our linear glass scales provide the bedrock for high-performance feedback. Manufactured using high-grade optical glass with low thermal expansion coefficients, these scales ensure measurement stability even during temperature fluctuations. By utilizing robust chrome-on-glass deposition, we guarantee superior signal fidelity and long-term durability, giving best-in-class systems the reliable baseline it needs for sub-micron precision.
Scalable High-Fidelity Feedback
Our glass scale architecture offers seamless integration for demanding metrology and automation applications. Available in a wide variety of lengths and accuracy classes, each scale is engineered to maximize the capabilities of PurePrecision™ optics. The high-contrast optical grating enables our sensors to achieve exceptional resolution while maintaining generous alignment tolerances, significantly reducing installation time and complexity, without compromising the linearity required for critical motion control.
