Compensation Unit
attocube systems AGRequest Info
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.
