UV Dose Mapping Spread with coldest grid-point dose of 2,400 mJ / cm²: a worked example

This scenario runs the uv dose mapping spread calculation on the strong side: coldest grid-point dose of 2,400 mJ / cm², with every other input held at its documented default. Use it after a profiling pass to quantify spatial dose variation across a fixture, belt width, or batch oven floor.

The inputs for this scenario

  • Coldest grid-point dose (cold spot): 2,400 mJ / cm² (raised for this scenario; the documented default is 950)
  • Hottest grid-point dose (hot spot): 1,450 mJ / cm² (unchanged)
  • Average dose across the grid: 1,180 mJ / cm² (unchanged)

Working through the calculation

  • Applying the documented formula (Dose spread = max − min (mJ/cm²)) to the inputs above produces each figure below.
  • At this operating point the engine returns 0 mJ / cm² spread for variation from average, the number this scenario is built around.
  • At this operating point the engine returns 0 mJ / cm² for dose spread (max − min).
  • At this operating point the engine returns 2,400 mJ / cm² for cold spot dose.
  • At this operating point the engine returns 1,450 mJ / cm² for hot spot dose.

How this compares with the baseline

  • Against the tool's baseline example, where coldest grid-point dose sits at 950 mJ / cm² and the headline result is 42.37 mJ / cm² spread, this scenario comes in 100% below the baseline at 0 mJ / cm² spread.
  • Use it after a lamp or reflector change, during periodic uniformity checks, or when only part of a product shows cure defects. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Variation from average: 0 mJ / cm² spread (headline result)
  • Dose spread (max − min): 0 mJ / cm²
  • Cold spot dose: 2,400 mJ / cm²
  • Hot spot dose: 1,450 mJ / cm²
