AR Coating Cost at 110% batch share with ar coating: a worked example

What does the result look like when batch share with ar coating reaches 110%? The full calculation is worked below with real intermediate numbers. an estimator needs AR coating cost for a quote or production batch

The inputs for this scenario

  • Lenses receiving AR coating: 520 lenses (unchanged)
  • AR coating cost per lens: 6.75 $ / lens (unchanged)
  • Batch share with AR coating: 110 % (raised for this scenario; the documented default is 100)
  • Fixed AR setup and qualification cost: 480 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable AR coating cost = AR-coated lenses × AR coating cost per lens × batch share with AR coating) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,341 $ for total ar coating cost, the number this scenario is built around.
  • At this operating point the engine returns 8.35 $ / lens for average ar coating cost per lens.
  • At this operating point the engine returns 3,861 $ for variable ar coating cost.
  • At this operating point the engine returns 480 $ for fixed ar setup and qualification cost.

How this compares with the baseline

  • Against the tool's baseline example, where batch share with ar coating sits at 100% and the headline result is 3,990 $, this scenario comes in 8.8% above the baseline at 4,341 $.
  • A figure at this level is achievable when batch share with ar coating is genuinely sustained, not just peaked for a shift. It models one coating configuration; mixed AR stacks (hydrophobic, mirror, blue-cut) carry different per-lens rates and scrap risks, so run them separately rather than blending.

Results at a glance

  • Total AR coating cost: 4,341 $ (headline result)
  • Average AR coating cost per lens: 8.35 $ / lens
  • Variable AR coating cost: 3,861 $
  • Fixed AR setup and qualification cost: 480 $
