ILT offers ISO17025 accredited calibrations of all ILT Spectrometers / Spectroradiometers. Light Meter Calibration certificates and software updates are provided with calibration.
Our calibration software/database maintains all calibration records since the 1990s which allows ILT to:
- Notify customers when system calibration is due
- Provide an accurate history of all prior service
- Provide support during calibration audit
- Show trends in performance (stability or degradation)
ILT Spectrometer calibrations cover the range of 200 - 1700 nm. Single-source calibrations cover 200 - 350 nm, 350 - 1050 nm and 1000 - 1700 nm. In many instances dual source (multi-step / multi-lamp) calibrations are required to cover the full working/application range. ILT calibrations are NIST traceable and ISO17025 accredited.
Each Spectrometer calibration is unique to the exact configuration used during calibration. Any changes to optics including fibers, diffusers, lenses, filters, integrating spheres, etc., will impact the accuracy of the reading. ILT recommends every unique configuration have its own calibration.
ILT spectrometer calibrations start off with a wavelength calibration verification. Shifts in wavelength are not common, but are in most cases corrected with calibration or repair. ILT offers spectral calibration for Total Flux (power/Watts/nm), Irradiance (W/m2/nm) and Radiance (W/cm2/sr/nm). Photometric calculations such as Lumens, Luminous Intensity (cd - with user programmable distance), PAR (umol/m2/s), Lux and cd/m2, as well as CCT, CRI, DUV are calculated based on the Radiometric calculations.
