Lens Cleaning Ultrapure Water Systems - 2025 Technical Guide

Why 18.2MΩ·cm Water is Critical for Optical Lens Manufacturing

✔ Eliminates micro-scratches - 0.2μm particle filtration prevents surface damage

✔ Prevents mineral residues - Zero TDS ensures spot-free drying

✔ Maintains coating integrity - Neutral pH protects delicate anti-reflective layers

✔ Reduces rejection rates - 99.8% first-pass yield with proper water quality

Industry Fact: 90% of optical lens manufacturing defects originate from impure cleaning water
