Abstract

The paper presents main characteristics of the device for calibration of line scales and measurement uncertainty evaluation by GUM and MCS method. As a part of research on the impact of measurement uncertainty the following was investigated: the position of laser light sources and optical components, minimizing Abbe's error, the determination of the middle line of line scales, alignment of line scale and laser beam, straightness movement of table, pitch, roll and yaw angles, environmental conditions affect the laser wavelength and the geometry of device and the impact of losing focus while moving of table. Measurement uncertainty evaluation has been validated in comparison measuremens EURAMET Key Comparison, EURAMET.L-K7 ''Calibration of line scales''.
