Precise & Traceable Calibration - ISO 17025

You can rely on the calibration in precision and traceability.

Gigahertz-Optik’s ISO/IEC 17025 calibration laboratory is accredited by DAkkS (D-K-15047-01-00), meeting ISO/IEC 17025 specifications for spectral responsivity and spectral irradiance.

The device offers different calibrations saved in the device:
  1. Calibration using a specially developed reference lamp with 2pi illumination. This gives you precise measurement of the luminous flux of diffusely emitting UV LEDs.
  2. Calibration for sources with narrower illumination characteristics.
  3. Optional calibrations on an external sphere, illuminacne adapter, etc.
