ISO 17025 calibration laboratory of Gigahertz-Optik for radiometry and photometry

Calibration and Testing Laboratory      Enabling Accuracy Gigahertz-Optik

An Introduction to our ISO 17025 Accredited Laboratory:

  • Many years of experience in the calibration laboratory, with ever-increasing know-how since 1993
  • Highly qualified personnel who receive regular internal training by experts 
  • Calibrations performed by engineers and technicians 
  • Calibrations supported by proprietary automated software solutions 
  • Measurement uncertainty determination according to the latest CIE 198 standard 
  • Traceable calibrations through DAkkS accreditation (D-K-15047-01-00)
  • The DAkkS* laboratory fully complies with DIN EN ISO/IEC 17025:2018
  • Regular participation in round robin comparisons
  • Complete device history for own products dating back for at least 10 years
  • Comprehensive calibration certificates, also for factory calibrations, including traceability and calibration uncertainties
ISO17025 traceable accredited
Extensive Equipment:
  • Entire laboratory temperature-controlled with a total size of over 300 m²
  • Optical setups according to the highest standards (irradiance, radiant intensity, radiant flux, radiance, illuminance, luminous intensity, luminance, as well as spectral quantities from UV to IR)
  • 10m optical bench for linearity measurements, calibration of working standards, etc.
  • Integrating spheres of various sizes – detector spheres for luminous flux and radiant power measurements as well as uniform light sources as luminance and radiance standards
  • Goniometer for reference measurements of luminous flux and light distribution curves
  • Traceable photometric standards from PTB or NIST
  • DAkkS-traceable calibrated current source
  • Climatic chamber (temperature and humidity) for the investigation and optimisation of own products
  • Variable-frequency laser (OPO) for spectral investigations of the highest quality, such as scattered light matrix determination of array spectroradiometers or spectral sensitivity measurement that are not influenced by the optical bandwidth of the illumination source
  • Various double monochromators from UV to IR for precise and low-scatter calibrations
  • Separate lamp and measuring rooms 
  • We meet the increasing requirements placed on the quality and the reliability of our products, for example by accelerated artificial ageing with respect to temperature and UV irradiation.
  • Wide range of necessary electrical measurement equipment (multimeters, digital and analogue oscilloscopes, frequency generators, power sources, etc.)
