Proper lens maintenance is essential to ensure optimal performance and prolong the life of your Fusion Laser system. Over time, dust, smoke, and debris can accumulate on the lens, reducing beam quality and potentially causing damage. Regular cleaning helps maintain consistent cutting and engraving results while protecting critical optical components. Always follow the recommended cleaning procedures carefully to avoid scratching or damaging the lens surface. The increased aperture lens functions the same as the standard lens. Follow the same cleaning procedure for both types.
- Clean the lens and mirrors daily as part of your routine maintenance.
- Perform a more detailed cleaning once a month, especially to access hard-to-reach areas like the bottom of the lens.
Daily Maintenance Cleaning

Repeat the same process to clean both sides of the lens.
-
Install the lens back into the carriage.
Monthly Detailed Cleaning
-
Remove the lens cone.
-
Remove the brass air fitting with a 7/64″ Hex wrench.
-
Remove the outer lens tube.
Note: There is a spring inside the outer lens tube.
-
Carefully remove the inner lens cone.
-
Clean the bottom side of the lens using a cotton swab and lens cleaner.
-
Reassemble the lens.
Note: Make sure the notch on the internal cone aligns with the hole on the side of the lens tube during reassembly.
Additional Optics
In addition to the carriage-mounted optics, the Fusion Laser system includes multiple steering mirrors located along the beam path. These mirrors are essential for accurately guiding the laser beam from the source to the lens. While they don’t require daily cleaning, it’s important to inspect and clean them periodically as part of your maintenance routine. Use the same lens-safe cleaning solution and a high-quality cotton swab. Accessing these mirrors may require removing panels or covers. Always ensure the system is powered off and follow all appropriate safety procedures during cleaning.
