Spectral UV and Visible Irradiance Measurements


Precision Photometrics offer an onsite service for spectral irradiance measurements of solar simulator sources and photo-stability cabinets, using a high precision double-monochromator spectroradiometer with calibration traceable to NPL standards.


Measurements include:-

  • Spectral Irradiance (250-800nm)
  • UV Irradiance (290-400nm)
  • UVA & UVB Irradiances
  • UVA/UVB ratio
  • Global Irradiance (300-800nm)
  • Illuminance (Lux)
  • Sample Tray Uniformity and Contrast
  • Lamp Output Linearity
  • Internal & External Radiometer Calibrations
