Precision at your fingertips.
Our Optical Encoders are the most accurate, highest resolution in the market, up to 1.2 nm. This unprecedented level of precision eliminates velocity ripple and ensures exceptional signal stability, even in the most dynamic motion control applications. By delivering virtually zero positional error, our technology empowers engineers to design systems with superior smoothness and exact repeatability, redefining the limits of what is mechanically possible.

Accuracy and precision
While many optical encoders are limited to cleanroom environments, Novanta’s optical encoders are engineered to bridge the gap between laboratory precision and real-world industrial durability. Through proprietary MicroE technology, we deliver high-resolution feedback that maintains integrity under conditions that typically cause traditional optical sensors to fail.

Built-in technology
Novanta’s optical encoders use PurePrecision™ and VeraPath™ technologies for the most reliable and accurate position readings. This combination allows engineers to achieve metrology-grade performance within an incredibly compact and lightweight footprint. Because the technology is tolerant of wider mechanical gaps and alignment shifts, you can design smaller, lighter motion control systems without the need for bulky, heavy housings or complex calibration routines, significantly reducing your overall time-to-market.
