UV Dose Uniformity with minimum dose reading of 2,400 mJ / cm²: a worked example

What does the result look like when minimum dose reading reaches 2,400 mJ / cm²? The full calculation is worked below with real intermediate numbers. Use it after a profiling pass to prove the cold corner of a fixture or belt still receives enough dose, or to justify reflector / lamp-spacing changes.

The inputs for this scenario

  • Minimum dose reading (cold spot): 2,400 mJ / cm² (raised for this scenario; the documented default is 950)
  • Maximum dose reading (hot spot): 1,450 mJ / cm² (unchanged)
  • Average dose across the cure surface: 1,200 mJ / cm² (unchanged)

Working through the calculation

  • Applying the documented formula (Spread = max dose − min dose (mJ/cm²)) to the inputs above produces each figure below.
  • At this operating point the engine returns 0 % non-uniformity for dose non-uniformity, 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 minimum reading (cold spot).
  • At this operating point the engine returns 1,450 mJ / cm² for maximum reading (hot spot).

How this compares with the baseline

  • Against the tool's baseline example, where minimum dose reading sits at 950 mJ / cm² and the headline result is 41.67 % non-uniformity, this scenario comes in 100% below the baseline at 0 % non-uniformity.
  • A figure at this level is achievable when minimum dose reading is genuinely sustained, not just peaked for a shift. It only reflects the specific points you measured; if your grid misses a shadowed edge or a reflector dead zone, real uniformity is worse than the number suggests.

Results at a glance

  • Dose non-uniformity: 0 % non-uniformity (headline result)
  • Dose spread (max − min): 0 mJ / cm²
  • Minimum reading (cold spot): 2,400 mJ / cm²
  • Maximum reading (hot spot): 1,450 mJ / cm²
