Optical Power Meter Calibration in Denmark

DFM in Denmark provides accredited optical power meter and light source calibration with traceability to national standards, covering visible and infrared wavelengths. Accredited Calibration ServicesDFM (Danish Fundamental Metrology) is the national laboratory for optical radiometry in Denmark and offers accredited calibration of optical power meters and light sources with traceability to the Danish primary standard. Their services include: Visible wavelength range: 476, 488, 514, and 550–860 nm, power range 10 nW – 2 mWNear-infrared (NIR) range: 800–1650 nm, power range 50 µW – 200 mWLinearity measurements: 1310 or 1550 nm, power range 50 µW – 200 mWWavelength calibration: 1295–1560 nm using lasers stabilized to molecular reference linesRelative Intensity Noise (RIN) measurement: 400–1800 nm, bandwidth 25 kHz – 150 MHz All calibrations are performed according to DANAK Accreditation Reg.

Nr. 255 and DFM's ISO 9001 certified quality system.

Calibration Standards and Traceability

Calibration is performed by comparing the device under test (DUT) to a working standard, which is in turn calibrated against a national standard, ensuring traceability and compliance with international standards. This ensures that optical power meters and light sources meet precise measurement requirements for research, telecommunications, and industrial applications. Additional ServicesOTDR instrument calibration: Length calibration for 1310 nm and 1550 nm lasersUV light measurement: Traceable characterization of UV LEDsFree-space and fiber optic power meter calibration: ISO/IEC 17025 or ISO 9001 accredited, including linearity and detector cleanliness checks Lamp-based calibration sources: NIST-traceable sources for spectral irradiance, radiance, or luminance, suitable for spectroradiometers and photometers How to Access ServicesFor calibration outside the standard ranges or for custom requirements, DFM encourages direct contact to discuss specific needs.

This ensures that specialized instruments or unusual wavelength/power ranges can be accommodated.

Summary

In Denmark, DFM provides comprehensive, accredited calibration services for optical power meters and light sources, covering visible, NIR, and UV ranges, with traceability to national standards. These services are essential for ensuring accuracy, reliability, and compliance in optical measurements for industrial, research, and telecommunications applications.
