As the core component of optical equipment, the surface cleanliness of lenses directly determines imaging precision—even a 0.1-micron dust particle or a single residual fiber can cause image distortion or coating damage. Ordinary cleaning cloths, with their coarse texture and high dust generation, fall far short of meeting these stringent demands. The Lidel ultra-fine polyester fiber Class 100 cleanroom cloth is precisely the professional cleaning solution tailored for lens manufacturing. This cloth addresses industry pain points with its core advantages: woven from 0.08-micron ultra-fine polyester fibers at 500 fibers per square millimeter, it employs capillary adsorption to powerfully capture fingerprints, oil residues, and 0.3-micron dust particles from lens surfaces—achieving 8 times the cleaning efficiency of ordinary cotton cloth. Strictly adhering to ISO Class 5 cleanroom standards, each cloth undergoes six cycles of washing with 18 MΩ high-purity water followed by vacuum drying. This process ensures ion residue <1 ppm and particle emission ≤10 particles/m², minimizing secondary contamination at the source. Addressing the delicate nature of lens coatings, the product employs ultrasonic edge sealing for smooth, burr-free edges. It guarantees 100% lint-free wiping and can safely contact optical surfaces without causing scratches. It offers dual-use flexibility for dry and wet cleaning: dry wiping efficiently removes dust, while wet wiping with optical-grade cleaning solution effortlessly eliminates stubborn stains. Its soft, breathable material maintains precise tactile feedback even when worn with gloves. As a preferred brand in the optical industry, it is widely used in production scenarios such as camera lenses, automotive lenses, and industrial optical lenses. With its high cleanliness and strong protective properties, it helps enterprises improve product yield rates, making it an indispensable professional cleaning companion for lens production.
