Snail Tools High-Transmission Fiber Laser Protection Lens (D20mm x T3mm)

Snail Tools | D20xT3 Protection Lens for Laser Cutters

For GTA metalworking operations where cut quality and machine uptime are paramount, the Snail Tools D20xT3 Protection Lens is the essential optical barrier. Installed within the laser cutting head, this lens shields the expensive focusing optics from splatter, dust, and debris generated during the cutting process.

Our protective windows are manufactured from high-grade Fused Silica, ensuring exceptional clarity and durability under intense thermal load.

Key Features for Canadian Metal Fabricators:

• Optimal Specifications: Precisely sized at $20\text{mm}$ Diameter and $3\text{mm}$ Thickness (D20 T3) for seamless integration into most common fiber laser systems.

• High Transmission (HT): Features a specialized Anti-Reflective (AR) coating optimized for the fiber laser wavelength ($\sim 1064\text{nm}$), ensuring minimal laser power loss and maximum cutting efficiency.

• Superior Durability: The Fused Silica material offers high damage threshold and thermal stability, allowing the lens to withstand the power demands of multi-kilowatt lasers used in heavy-duty manufacturing.

• Crystal Clarity: Maintaining clean optics is crucial for beam quality. This lens provides a transparent barrier that preserves the integrity of the laser beam, resulting in precise and repeatable cuts.

• Cost Efficiency: Using Snail Tools quality protection lenses is the most cost-effective way to extend the lifespan of your much more expensive focusing optics.
