The SET‑HD100 is a self-compensating rotary encoder system designed for high-precision calibration of rotational axes, delivering exceptional accuracy and repeatability.

Using advanced Laserscale technology, the system compensates for installation errors and provides traceable measurement data, making it ideal for machine tool calibration and performance verification.

Key features

Ultra-high angular accuracy – Achieves accuracy up to ±0.1 arcsec with resolution as fine as 0.0012 arcsec
Self-compensating measurement – Automatically corrects installation and alignment errors for reliable calibration
High reproducibility – Delivers consistent measurement results through non-contact design
Traceable calibration – Supports calibration traceability with certified measurement references
Portable and easy to use – Compact system suitable for on-site calibration applications

How it works

The SET‑HD100 uses a laser-based rotary encoder system to measure angular position with extremely high precision.

Through its self-calibration algorithm, the system compensates for mechanical and installation errors, enabling accurate measurement even in non-ideal mounting conditions.

This allows users to:

Verify rotary axis accuracy
Detect positioning errors
Improve machine performance
Ensure long-term measurement reliability

Typical applications

CNC rotary axis calibration
Machine tool verification and acceptance testing
Precision engineering and metrology
Performance validation of high-accuracy systems

Why choose the SET-HD100

Eliminates installation-related measurement errors
Provides industry-leading angular accuracy
Supports traceable calibration processes
Enables reliable machine performance verification

Laserscale allows high stability against environmental change such as pressure and temperature with the combination of high resolution, diffraction grating and a sensor head with symmetric optical path. Signal wavelength 1.24 arcsec = 6.0 μrad (250 nm on the circle of 42 scale) is electrically interpolated to the resolution of 0.0012 arcsec = 5.9 nrad (0.25 nm on 42) at the low noise level.
