MiraWIPE® LS
Low-Lint Cleanroom Microfiber Wipers for Precision Optics & Laser Cleaning
Engineered Optics Cleaning Wipers for Advanced Laser and Optical Manufacturing
In advanced optics fabs, high-power laser systems, EUV/DUV lithography, and precision optical coating operations, surface cleanliness directly defines performance, yield, and reliability. A single sub-micron particle, fiber fragment, or solvent streak can scatter light, reduce laser-induced damage threshold (LIDT), or compromise multi-million-dollar optical components.
MiraWIPE® LS is a purpose-engineered low-lint microfiber wiper designed specifically for laser optics cleaning and critical optical surfaces. Its ultra-soft microfiber construction and continuous heat-sealed edge support industry-accepted drag-and-wipe and drop-and-drag solvent cleaning techniques—without scratching, fiber release, or residue.

High-Capillary Microfiber
Efficient one-pass removal of particles and organic films.
Extremely Low Lint & NVR
Meets cleanliness expectations of leading optics and laser OEMs.
Industries
MiraWIPE® microfiber cleanroom wipes are used across semiconductor manufacturing, pharmaceutical and GMP sterile manufacturing, medical device production, biotechnology and biologics processing, optics and precision lens manufacturing, flat panel display manufacturing, hard disk drive and data storage production, compound semiconductor fabrication, solar and photovoltaic manufacturing, and other advanced microelectronics and high-precision cleanroom environments where strict contamination control is required.
Applications for MiraWIPE® LS Optics Cleaning Wipers
- High-power laser optics (fs, ns, CW) and transport mirrors
- EUV & DUV lithography lenses, reticles, and masks
- SEM-adjacent optical components and metrology optics
- Space and astronomy optics (aluminized or silvered)
- Optical substrates prior to PVD, IBD, or ALD coating
- AR-coated windows, beamsplitters, and polarizers
- Semiconductor, aerospace, and defense photonics manufacturing
Why Optics and Laser OEMs Specify MiraWIPE® LS
Heat-Sealed Edge for Zero Fiber Release
Unlike ultrasonically cut wipes, MiraWIPE® LS features a continuous heat-sealed perimeter that cannot fray, split, or shed fibers. This is critical when cleaning:
- High-reflectivity (HR) mirrors
- Tight apertures and cavity interiors
- Edge-sensitive optical components
Preventing fiber introduction helps protect uptime in SEM, lithography, and laser metrology tools where fiber-related defects often lead to repeat cleaning or tool recovery.
Ultra-Soft Microfiber for LIDT-Critical Laser Optics Cleaning
The microfiber surface is engineered for near-zero pressure cleaning (<50 g), allowing safe contact with:
- LIDT-critical laser optics
- AR- and dielectric-coated lenses
- EUV & DUV optical elements
The fabric conforms naturally to flat, curved, and free-form optics, enabling consistent single-pass drag cleaning without micro-scratching.
Proven Compatibility with Optical-Grade Solvents
MiraWIPE® LS is fully compatible with the solvents most commonly specified by optics and laser OEMs, including:
- Spectroscopic-grade Methanol
- Ethanol
- Isopropyl Alcohol (IPA)
- Acetone
- Hexane and approved solvent blends
The microfiber maintains tensile integrity, does not swell, and releases no measurable extractables, supporting ultra-low residue requirements (<1 ng/cm²) demanded in advanced optics and SEM-adjacent processes.
High-Capillary Microfiber Structure for Effective Contamination Removal
A star-shaped, asymmetrical microfiber geometry enhances capillary uptake and particle entrapment during solvent-assisted wiping. This enables efficient removal of fingerprints, airborne fallout, and thin organic films in one or two controlled passes—minimizing re-contamination risk.
Cleanroom-Certified for Optical and Semiconductor Manufacturing
MiraWIPE® LS is manufactured and packaged for ISO Class 5 / Class 100 cleanroom environments and lot-tested using industry-recognized methods (LPC, Helmke Drum, optical microscopy). This ensures:
- Extremely low lint and particle contribution
- Consistent low NVR performance
- Suitability for optics fabs supporting SEM, lithography, and laser systems
