1. Introduction and Overview
This manual provides essential information for the proper use and maintenance of KSK Laser Source Protective Windows Lenses. These lenses are designed to protect the sensitive optical components of various fiber laser sources, including RECI, MAX, Raycus, BWT, IPG, and GW, during cutting and welding operations. Made from high-quality pure copper, these protective caps ensure durability and optimal performance, safeguarding your laser equipment from debris and damage.
The protective window acts as a sacrificial element, preventing spatter, dust, and other contaminants from reaching the internal optics of the laser head, thereby extending the lifespan and maintaining the efficiency of your laser system.
2. Product Variants and Compatibility
KSK offers a range of protective lenses compatible with various laser sources. It is crucial to select the correct lens variant that matches your specific laser source model and dimensions. Key dimensions include diameter (D) and height (H).
Figure 2.1: Assortment of RECI protective lenses, showing silver and golden options with varying heights (e.g., 16.9mm, 17.5mm, 18mm) and a common diameter of 12.8mm.
Figure 2.2: Overview of protective lenses compatible with MAX, Raycus, RECI, BWT, IPG, and GW laser sources, illustrating diverse designs and sizes.
Specific RECI variants include:
- D12.8 H16.6 silver (non-original)
- D12.8 H17 gold (non-original)
- D12.8 H17.5 gold (original)
- D12.8 H16.9 gold (original)
- D12.8H17.5 U9.1 gold (original)
- D12.8 H18 gold (non-original)
Always verify the dimensions and compatibility with your laser source's specifications before installation.
3. Setup and Installation
Proper installation of the protective lens is critical for effective laser operation and safety. These lenses are typically designed to fit into the QBH protective connector of your fiber laser source.
- Identify the Correct Lens: Ensure you have the correct protective lens variant (e.g., D12.8 H17.5 gold) that matches your laser source's requirements. Refer to the specifications section or your laser source manual.
- Safety First: Before handling any laser components, ensure the laser system is powered off and locked out according to your facility's safety protocols. Wear appropriate personal protective equipment (PPE), including laser safety glasses.
- Prepare the Laser Head: Carefully remove the existing protective cap or access the QBH connector area of your laser head.
- Cleanliness: Ensure both the new protective lens and the mating surface on the laser head are free from dust, fingerprints, or any contaminants. Use a lint-free optical wipe and appropriate optical cleaning solution if necessary.
- Install the Lens: Gently insert or screw the protective lens into the QBH connector. Ensure it is seated correctly and securely, but do not overtighten.
- Visual Inspection: After installation, visually inspect the lens to ensure it is clean, undamaged, and properly aligned.

4. Operating Considerations
The KSK protective lens is a passive component designed to safeguard your laser system. Its "operation" is primarily about its presence and condition during laser use.
- Pre-Operation Check: Always ensure the protective lens is securely installed and clean before initiating any laser cutting or welding operations.
- Environmental Factors: While the lens protects against spatter and dust, operating in an excessively dusty or smoky environment can still lead to rapid contamination. Ensure proper fume extraction and a clean working environment.
- Impact on Laser Performance: A clean, undamaged protective lens will have minimal impact on laser beam quality or power. A dirty or damaged lens, however, can significantly degrade laser performance, cause beam distortion, and potentially lead to damage to internal optics.
5. Maintenance
Regular inspection and cleaning of the protective lens are essential to maintain optimal laser performance and prevent costly damage to your laser source.
- Frequency: Inspect the protective lens daily or after every significant period of laser operation, especially if working with materials that produce heavy spatter or fumes.
- Inspection:
- Power off the laser system and follow safety protocols.
- Carefully remove the protective lens.
- Examine the lens surface for any signs of dust, debris, spatter, scratches, cracks, or discoloration.
- Cleaning:
- If the lens is only lightly dusty, use a clean, dry air blower (optical grade) to remove loose particles.
- For fingerprints or light smudges, use a lint-free optical wipe moistened with a suitable optical cleaning solution (e.g., isopropyl alcohol or acetone, as recommended by your laser manufacturer). Wipe gently from the center outwards in a single stroke, then use a fresh part of the wipe for the next stroke.
- Avoid rubbing vigorously, as this can scratch the lens or leave residue.
- Replacement:
- If the lens shows any signs of scratches, cracks, pitting from spatter, or permanent discoloration that cannot be cleaned, it must be replaced immediately. A damaged protective lens can cause significant laser power loss and potentially damage the more expensive internal optics.
- Always keep spare protective lenses on hand.
6. Troubleshooting
Most issues related to the protective lens stem from contamination or damage. Here are common problems and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Laser Power / Weak Cut | Dirty or damaged protective lens. | Inspect and clean the lens. Replace if damaged. |
| Inconsistent Cutting/Welding Quality | Contamination or damage on the lens causing beam distortion. | Inspect and clean the lens. Replace if damaged. Ensure proper installation. |
| Visible Spatter/Debris on Lens | Normal wear and tear, insufficient gas assist, or improper cutting parameters. | Clean the lens regularly. Adjust gas assist and cutting parameters. Replace if pitting is severe. |
| Lens Overheating / Cracking | Severe contamination leading to absorption of laser energy, or incorrect lens type. | Replace the lens immediately. Ensure regular cleaning. Verify the lens is the correct type for your laser. |
