Wood is one of the most commonly applied materials that are used with laser cutters and engravers, and there are many reasons for that. Compared to other materials, it has relatively inexpensive options and looks fantastic when used with both desktop laser cutters and industrial laser cutters.

This article discusses the importance of maintaining clean optics in laser engravers, specifically mirrors and focus lenses, to ensure optimal performance. It explains how airborne particles, smoke, and debris from the laser cutting process can contaminate mirrors and lenses, leading to reduced efficiency, potential overheating, and permanent damage.

The article provides step-by-step instructions for cleaning the mirrors and lenses using isopropyl alcohol, proper tools, and techniques. It emphasizes regular cleaning and inspection to extend the lifespan of the equipment and maintain high-quality results.
