ILT Calibration Services

As our customers have adopted quality manufacturing standards such as ISO17025 and ISO9001, their need for annual NIST traceable re-calibrations has also increased. To meet this demand, ILT has expanded our calibration lab and our standard calibration service offering to include non-ILT light meter and system calibrations (the "C" part numbers on the calibration services Web page).
ILT can also scan 10mm cuvettes for transmission or absorbance ("CSTM" calibrations). 


Know how much light is getting through with ILT’s professional grade meters.


ILT sells radiometers and spectrometers that can be used to measure the spectrum and transmittance of light through objects such as glass, plastics, lenses, metal, thin film, window tint screens, sun glasses, light blocking fabrics and solar viewing glasses (as seen on the Today's Show segment on the upcoming solar eclipse). We cover the range from UV to IR and offer systems allowing calibrated or relative values. Systems include the ILT's Datalight or Spectrilight light measurement software at no additional cost.
