Traceable Calibrations

Photometers, Luxmeters, Spectroradiometers, Luminance Meters, Light Sources


The long motorized optical rail and large range of standard light sources enable versatile calibration services for luxmeters, photometers, and spectroradiometers with a calibrated, precision photometer / spectroradiometer. The calibrations are traceable to SI.

Measurement conditions with the radiation spectrum of the light source:
  • Illuminance Level: 1 - 30 000 lx
  • Wavelength range 250 - 1050 nm
  • LED-lamp 2700 K - 7000 K, Ra = 70-85
  • halogen lamp, adjustable to Illuminant A  (CCT = 2856 K)

Other traceable measurements are also possible, ask for more information!
