UV Radiometer Reading Calibration Correction with raw radiometer reading of 550 mJ / cm²: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop raw radiometer reading to 550 mJ / cm², then walk the calculation through step by step. Apply a calibration correction factor to a raw radiometer reading and compare the corrected number to a target dose.

The inputs for this scenario

  • Raw radiometer reading: 550 mJ / cm² (the input this scenario stresses; the baseline uses 1,100)
  • Radiometer calibration correction factor: 1.08 x (held at the documented default)
  • Target cure dose: 1,200 mJ / cm² (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Corrected dose = raw reading × calibration correction factor.
  • Corrected dose at part works out to 594 mJ / cm² (corrected) at these inputs, and this is the headline figure for the scenario.
  • Headroom over target dose works out to -606 value at these inputs.
  • Raw reading (uncorrected) works out to 550 mJ / cm² at these inputs.
  • Calibration correction factor works out to 1.08 x at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where raw radiometer reading sits at 1,100 mJ / cm² and the headline result is 1,188 mJ / cm² (corrected), this scenario comes in 50% below the baseline at 594 mJ / cm² (corrected).
  • The practical read: the gap between this scenario and the baseline is entirely attributable to raw radiometer reading, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The correction factor only compensates for the meter's own error; it cannot account for the meter being a different band, geometry, or optical window than the reference standard.
