Quality control
Every lens, measured.
Mechanical, chemical and optical tests before lenses leave the factory.

000# steel wool, ≥750 g load, 1,000 cycles. Haze increase must stay within 0.8%.
03
Salt-water boil
20 minutes in boiling 5% NaCl, then room-temperature water. No cracking or peeling allowed.
04
