MUNICH, Feb. 18, 2016 — Attocube Systems AG has announced the Environmental Compensation Unit (ECU), an automated device for ultraprecise distance measurements.
The ECU provides fully automated air refractive index correction down to the sub-parts-per-million range. When connected to an interferometer, the device automatically detects the absolute sensor/target separation, calculates actual air refractive index and compensates any incremental measurement.
Environments are recorded and stored for future reference.
