The NPL Optical Dimensional Standard 

High quality calibration scales are required for making traceable measurements with non-contacting imaging and vision measurement systems. NPL designs and calibrates a range of optical scales and reference patterns for quantitative microscopy, image analysis and non-contact measurement systems.

Our extensive range of measurement facilities provides sub-micrometer accuracy for the following types of scales:

• Stage Micrometers
  
  
• High Precision Line Scales
  
  
• Optical Dimensional Standard
  
  
• NPL Reference Stage Graticules
  
  
• X-Y Grid Plates
