The National Laboratory for Photometry and Radiometry offers calibration of optical materials.

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. 

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.

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.

The National Laboratory for Photometry and Radiometry offers calibration of fiberoptic equipment.

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. 

The scope of the national laboratory includes: 

• Responsivity of fiber optic detectors or power meters (850 nm, 1300 nm, 1550 nm)
• Wavelength of fiber optical sources (600 nm - 1550 nm)
• Wavelength of optical spectrum analysers (600 nm - 1550 nm)

Calibration of power meters are performed in comparison with a reference radiometer. Calibration of wavelength is performed using absorption lines in a gas cell. 

We also offer accredited calibration of: 

• Length scale for OTDR
• Loss deviation for OTDR
• Pulse characteristics for OTDR

The OTDR calibrations are not performed as part of the national laboratory but have separate accreditations. 

We are available for consultation with regard to fiber optic measurements and can also help with validation of equipment or measurement methods. 

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 or as an accredited calibration. 

The National Laboratory for Length and Dimensional Metrology offers calibration of HeNe-Laser sources at 633 nm.

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence 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 fulfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

Calibration of the object’s laser frequency is performed via heterodyne measurement against one of Sweden’s primary standards for optical frequency. The standards are Iodine-stabilized He-Ne lasers with a laser frequency in agreement with BIPMs recommended values for the realization of the metre in the mise en pratique.

The results from the calibration are:

• Measured vacuum wavelength
• Relative deviation from the specified vacuum wavelength
• Difference between longest and shortest measured wavelength
• Diagram showing the relative deviation of the vacuum wavelength from specified vacuum wavelength

Additionally the optical power is measured.

The laser frequency calibration certificate is issued under the CIPM MRA.

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.

If you are interested in calibrating environment sensors belonging to the laser system, please mention this when ordering the calibration.

We perform classifications of all types of lasers i accordance with SS-EN 60825-1.

Classification of a laser or laser product in accordance with SS-EN 60825-1 involves characterizing the laser with regard to output power, wavelength, pulse etc. Based on those measurements the product is assigned a laser class. The laser class determines e.g. what warning labels the product should have. We are also able to measure the divergence of the laser in order to calculate the laser hazard distance. 

In order for a product to be marketed it is required that the product is safe. SS-EN 60825-1 is one of the standards that laser products need to comply with in order to be handled safely. 

The classification is performed in accorance with applicable parts of method 0374 which is based on IEC SS-EN 60825-1:2014.

The results are presented in a report in english with an accreditation mark. The report also gives instructions about how to label the product and which information needs to be available to the user in the manual. 

RISE is also a CB Test Laboratory for IECEE and can upon request issue an IECEE-report for the test which can then be certified by IECEE through Intertek Semko.
