Laser window, xTool P3

The laser window for xTool P3, also called a laser head protective mirror, plays a key role in the proper operation of your engraver. Positioned at the front to face smoke and microparticles generated during engraving and laser cutting, it protects internal optical components from contamination and premature wear.

Over time, this window can become clouded, scratched, or lose transparency, especially with intensive use on materials like wood, leather, or certain plastics. A degraded mirror results in reduced effective power, decreased precision, and sometimes excessive laser head heating. Replacing this part restores a clean and well-focused beam.

Specifically designed for the xTool P3, this replacement window offers high light transmission while maintaining excellent resistance to deposits and thermal stress from CO₂ lasers. Installation is simple and requires no complex adjustments, making it an accessible maintenance operation.

Usage and maintenance tips

To extend the life of your laser window, it is recommended to:

• Regularly check the condition of the window, especially after long engraving sessions.
• Clean only with laser optics-safe products, avoiding harsh solvents.
• Replace the window as soon as persistent marks or noticeable performance loss appear.

A clean and well-maintained window is often underestimated, but it is essential for ensuring sharp engraving.
