Certified Accuracy

attocube ’ s IDS3010 was tested by the National Metrology Institute of Germany ( PTB ). The accuracy of the interferometers has been confirmed at various pressure , humidity and temperature conditions over several days , thus also confirming the high performance and reliability of attocube ’ s ECU ( environmental compensation unit ). An accuracy of typically betterr ± 1 ppm can be achieved in air .

The figure above shows the systematic measurement error and the measurement uncertainty of the IDS as certified by the PTB . They depend on the working distance . The blue line represents a measurement error of 0.4 ppm that surrounds the other lines , while the average systematic error is always lower than 0.19 ppm .
