Stage Micrometers

Stage micrometers 

NPL offers a UKAS accredited service for the calibration of stage micrometers (and other linescales or calibration standards) up to 150 mm in length. Scales are measured using a microscope with a travelling stage. The displacement of the stage is measured by means of a helium-neon laser interferometer, providing an uncertainty of 0.2 µm or better for scale length of 50 mm with direct traceability to the metre.
