Protection Window FS-313 1.654"DIA 0.354"THK BAR/BAR@0.9-1.1um

Mazak Protection Window

Laser cutting generates airborne debris, metal spatter and fumes that can damage sensitive optical components. Alternative Parts, Inc. (API) supplies Mazak-compatible protection windows engineered to shield focusing lenses and mirrors from contamination.

Protection Window Specifications and Function

This protection window features a 1.654-inch diameter and 0.354-inch thickness, optimized for FS-313 laser systems. The window features an anti-reflective coating on both surfaces across the 0.9-1.1 micrometer wavelength range, ensuring maximum beam transmission with minimal optical loss. Positioned between the cutting head and processing zone, protection windows act as sacrificial barriers that absorb debris impact.

When protection windows become scratched or coated with residue, beam quality degrades. Regular inspection and timely replacement maintain optimal laser performance.

Key Benefits of API Protection Windows

Strategic window replacement as preventive maintenance reduces unplanned downtime and preserves cutting accuracy, along with other benefits:

• Optical clarity: Anti-reflective coatings maximize beam transmission while the window protects against debris accumulation.

• Precise specifications: Manufactured to exact diameter and thickness standards for proper fit in Mazak systems.

• Cost-effective protection: Replacing windows extends the service life of expensive internal optics.
