Laser Optics for Fiber Laser & YAG
Lenses and Protective Windows for 1060–1080 nm
Fiber lasers and YAG lasers operate at wavelengths around 1060–1080 nm (standard is 1070 nm), requiring specialized optics. Components for CO₂ lasers are not compatible with this wavelength range.
Materials for Lenses and Protective Glass
Common materials include:
BK7 glass – standard grade, good optical clarity
FS (Fused Silica / Quartz) – superior thermal stability, preferred for industrial use
Fused silica is typically used due to its resistance to rapid temperature changes and extended lifespan.
Premium Options: Sapphire & Diamond
For demanding environments, sapphire glass offers excellent scratch resistance and high thermal durability. While more expensive than FS, it is ideal where optical performance and longevity are critical.
Diamond optics are the ultimate choice – exceptionally durable, smudge-resistant, and easy to clean. If kept clean, diamond lenses or protective windows can last indefinitely. However, they are harder to source and significantly more costly.
Optical Coatings
Most lenses and windows feature AR (Anti-Reflective) coatings to minimize reflection and maximize transmission, which is vital in high-power fiber laser applications.
Custom Dimensions Available
We supply protective windows in any size, tailored to your machine. Please provide:

Cleaning & Maintenance of Fiber Laser Optics
For daily cleaning, use:
Isopropyl alcohol (IPA)
Lint-free wipes and cleaning swabs designed for laser optics
💡 For heavier contamination:
Start with 20% diluted acetic acid
Follow up with chemically pure acetone
Always clean in a dust-free environment. Avoid removing optics in industrial surroundings – contamination can enter the cutting head and require costly cleanroom-level cleaning.
