High‑Performance Interpolator for Ultra‑Precision Encoder Systems

The BD700 is a high-performance interpolator designed to maximise the resolution, accuracy, and performance of Magnescale Laserscale systems.

Compatible with a wide range of Magnescale encoder heads—including BS78, BL57, BH20, BH25, BL50H and other Laserscale series—it converts analogue signals into high‑resolution position data for advanced motion control and metrology applications.

Key Features

Ultra‑high resolution output – Enables resolutions down to 2.1 pm when used with compatible Laserscales such as the BS78
Exceptional interpolation accuracy – Achieves ±10 pm interpolation accuracy through real-time signal correction
Dual‑axis capability – Outputs synchronised position data for two axes simultaneously
Multi‑interface compatibility – Supports serial communication (FANUC, Mitsubishi, Yaskawa, BiSS), A/B quadrature, analogue, and USB
Improved system accuracy – Short-range error compensation enhances overall cumulative accuracy

How it works

The BD700 processes high-frequency analogue signals from Laserscale encoder heads and converts them into high-resolution digital output.

Real-time interpolation increases signal resolution significantly
Built-in compensation corrects signal distortion and improves measurement accuracy
Output data can be transmitted directly to CNC systems, motion controllers, or PCs
