Calibration of light sources at The National laboratory

The National Laboratory for photometry and radiometry offers calibration of light sources for photometric and radiometric applications.


The National Laboratories are responsible for maintaining the national reference standards for each measurement quantity and  spreading metrological competens and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden. 

A calibration performed at a national laboratory fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 


Calibration of light sources involve the following parameters: 

  • Luminous intensity (Candela)
  • Luminous Flux (Lumen)
  • Correlated Colour Temperature (Kelvin)
  • Spectral Irradiance (W⋅m-2⋅nm-1, 250 nm - 2500 nm)

The calibrations are performed in accodance with applicable international standards and recommendations. 

Calibrations are generally performed in comparison with the National Laboratories reference sources or through measurements with a reference instrument. For information about measurement uncertainty, traceability or other details about the calibrations please contact one of the contact persons listed below. 

The calibration takes place at the laboratory for photometry and radiometry in Borås. 


The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.
