How to Safely Clean Optical Glass Lenses Without Scratching Anti-Reflection Coatings
How to Safely Clean Optical Glass Lenses Without Scratching Anti-Reflection Coatings Cleaning optical glass lenses safely without scratching anti-reflection coatings requires a specific sequence: dry dusting with compressed air or a blower, followed by a solvent-based wipe using lens-grade tissue and approved cleaning solutions, always moving in a single direction with minimal pressure. Most lens damage doesn't come from use—it comes from improper cleaning. A single gritty particle dragged across an AR-coated surface can leave a permanent scratch that degrades transmission and increases scatter. This guide walks through the exact materials, step-by-step procedure, and common mistakes to avoid so your precision optics keep performing to spec. Key Takeaways Always remove loose particles with dry air before any liquid touches the lens surface Use only lint-free lens tissue or microfiber cloths designed for optical surfaces Clean in one direction, never circular motions, to avoi...
