PossibleMulti-coat composition uncertainty
Where these two actually differ
- We flag Multi-coat composition uncertainty on the Sigma and not on the B+W.
- The B+W is Optical glass lens with multi-coated optical surfaces where the Sigma is Optical glass with unspecified multi-coatings, which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the B+W is the one to buy.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
