Keep your laser cleaning machine operating at peak efficiency and prevent costly damage to your critical optical components. Our high-performance laser protective lenses (also known as protective mirrors) are engineered as a crucial consumable to shield the internal focusing lens from debris, smoke, and spatter generated during high-power cleaning applications like metal rust removal and paint stripping.
The longevity and performance of a protective lens are fundamentally determined by its material. Our lenses utilize high-purity Fused Quartz Glass , meticulously chosen for its superior optical, thermal, and mechanical properties.
Exceptional Light Transmittance: Achieves over 99.5% transmission for the typical 1064nm fiber laser wavelength, ensuring minimal power loss and maximum cleaning efficiency.
High Thermal Stability: Quartz offers excellent resistance to thermal shock, crucial for high-power continuous or pulsed laser operations, preventing lens cracking or warping.
Robust Durability: The substrate undergoes precision grinding and polishing, followed by a double-sided Anti-Reflection coating to significantly reduce back-reflection and enhance resistance against splashes, contaminants, and high-energy particles. This premium coating is key to extending the lens's operational life.
Our protective lenses are manufactured with precision dimensions to ensure perfect fitment and seamless integration with various popular laser cleaning heads (e.g., handheld fiber laser cleaners).
Common Diameter (D):30mm, 38mm, 40mm, 43mm(Please select the exact diameter compatible with your machine's laser head.)
Common Thickness (T): 2mm, 3mm, 5mm,(Thickness ensures stability and correct focal point setting.)
Wavelength: Designed and coated for optimal performance at the standard 1064nm wavelength of fiber lasers, typically supporting a range of 900nm - 1090nm.
While protective lenses are consumables, their service life is directly related to quality and operational practices.
Protection against Damage: Our superior double-sided coating dramatically slows down the accumulation of cleaning residue, significantly extending the life compared to uncoated or single-coated options.
Maximizing Lifespan: With proper maintenance and optimal operating conditions (e.g., sufficient assist gas flow), our lenses can provide hundreds of hours of reliable protection.
Timely Replacement: The true lifespan depends on the intensity of the application (e.g., heavily rusted metal generates more debris). Routine inspection is mandatory; replace the lens immediately upon noticing signs of scratches, pits, burns, or excessive dirt build-up that cannot be cleaned, to prevent damage to internal optics.
Simple, consistent maintenance is vital for maintaining high performance and extending the lens's life.
Routine Inspection: Visually check the lens surface before and after each long cleaning session for debris or damage.
Cleaning Procedure:
Only use specialized optical lens wipes/cotton swabs and high-purity industrial-grade alcohol (IPA - Isopropyl Alcohol).
Gently wipe the surface using a linear or circular motion from the center outward. Never reuse a swab.
Ensure the lens is completely dry before restarting the laser.
Storage: Store spare laser protective lenses in their sealed, original packaging in a clean, dry, and dust-free environment.
Choosing the right lens is essential for performance and safety.
Check Your Machine Manual: The most reliable source for the correct diameter and thickness is your laser cleaning machine or laser head manual. Look for the "Consumables" or "Optical Components" section.
Verify Dimensions: Physically measure your existing protective lens if the manual is unavailable. The size must match exactly.
Confirm Wavelength: Ensure the lens is optimized for the $1064nm$ wavelength of your fiber laser source.
Compatibility: If applicable, verify compatibility with your specific machine model (e.g., compatible with 100W, 200W, 1000W, 2000W fiber laser cleaner systems).
