Purpose
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.
Method
The national laboratory calibrates a wide range of optical materials. The calibrations involve the following measurement quantities:
- Transmittance
- Aborbance or optical dampening
- Reflectance
- Wavelength
- Index or refraction
Typical objects that are calibrated include:
- Neutral density filters
- Smoke meter filters
- Band-pass filters
- Interference filters
- Standards for absorbance, transmittance, reflectance or wavelength
- Cuvettes
- Optical liquids
- Colour standards
- Mirrors
Objects are calibrated using a spectrophotometer in a range of 200 nm to 2500 nm.
Index of refraction is calibrated using an Abbe refractometer.
The calibrations takes place at the laboratory for photometry and radiometry in Borås.
Deliveries
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.
