High precision line scale 

Line scales offer a practical means of traceably verifying the measurement performance of optical measurement equipment.

NPL-designed high precision line scales are available in lengths from 100 µm to 400 mm. Scales can be traceably calibrated by NPL to 0.1 µm uncertainty using a purpose-built travelling stage microscope fitted with dual laser interferometer system.
