During laser operation, smoke and debris are generated, which can accumulate on the protective lens and nozzle. If not cleaned regularly, this buildup can reduce laser power, cause incomplete cuts, degrade engraving quality, or even damage the lens.
- Focusing Lens: Mounted inside the laser module, this lens concentrates the laser beam into a tiny spot to improve cutting depth and engraving precision. It’s one of the most critical optical components in the module.
- Nozzle: Located at the outermost part of the laser module, usually cone- or cylinder-shaped with a small opening. It directs airflow to blow away smoke and debris, helping to keep particles out of the module.
- Protective Lens: Positioned between the nozzle and focusing lens, usually a transparent glass disc. It blocks dust and debris from entering the module, protecting the focusing lens. The protective lens is replaceable, making maintenance easier and reducing costs.
Tip: The protective lens acts as a barrier, keeping the focusing lens completely isolated from the external environment. During routine maintenance, you only need to clean the outer protective lens.
¶ 1. Prepare the Tools
- Cotton swabs or tissues
- Alcohol
¶ 2. Cleaning Procedure
¶ Step 1: Remove the Laser Module
 |
 |
|---|---|
Disconnect the pump tube and laser module cables in order |
Pull down the handle that secures the module, then gently lift the laser module out of its slot |
¶ Step 2: Remove the Protective Lens
- Remove the nozzle first, then unscrew the protective lens from the module.
¶ Step 3: Clean the Lens and Nozzle
 |
 |
|---|---|
Dip a cotton swab in alcohol and gently clean the protective lens until it is clear |
Check the nozzle for clogs; if blocked, carefully clear the opening |
¶ Step 4: Reinstall the Lens and Nozzle
- Screw the protective lens back onto the module, then attach the nozzle.
¶ Step 5: Reassemble the Laser Module
 |
 |
|---|---|
Place the laser module back onto the mounting block, then lift the handle to secure it |
Reconnect the module cables, then reattach the air assist tube |
