| Industry | Typical Equipment | Recommended Protection Plan |
| Automobile Manufacturing | Laser Welding Robot | 10 mm thick polycarbonate sheet with an outer diameter of 6 mm, providing protection against 1064 nm laser wavelengths and splash resistance. |
| Electronic Precision Processing | UV Laser Micro-etching Machine | 5 mm thick, OD5 UV-blocking specialty plate with 355 nm protection |
| Medical Cosmetology | Picosecond Laser Freckle Removal Device | 8 mm thick laminated sheet with an outer diameter of 6 mm (dual-band: 532 nm + 1064 nm) |
| Aerospace | High-energy laser surface treatment equipment | Custom sheet with a thickness of 15mm and an outer diameter of 7, featuring a 10.6μm coating and impact resistance. |
| Property | Laser Safety Polycarbonate | Laser Safety Acrylic (PMMA) |
| Impact Resistance | ✅ Excellent (Shatterproof) | ❌ Poor (Brittle, may shatter) |
| Scratch Resistance | ❌ Moderate (Requires coatings) | ✅ High (Harder surface) |
| Optical Clarity | Good (Slight tint in thick sections) | ✅ Excellent (Superior transparency) |
| UV Stability | ✅ Excellent (Minimal OD degradation) | ❌ Poor (Dyes degrade → OD loss over time) |
| Laser Protection Efficiency | Higher OD per mm (Thinner sheets suffice) | Requires thicker sheets for equivalent OD |
| Flame Resistance | ✅ Self-extinguishing (UL94 V-0/V-2) | ❌ Burns readily (unless FR-treated) |
| Long-Term OD Reliability | ✅ Stable for decades | ❌ Risky (Degrades under UV/light exposure) |
| Cost | ❌ Higher (30–50% more) | ✅ Lower |
| Weight | Lighter (Thinner sheets achieve high OD) | Heavier (Thicker sheets needed) |
| Best For | • High-impact environments (industrial) | • Low-impact labs (visible lasers) |
Crack the sheet.
Create unprotected edges.
Compromise OD near cut lines.
→ Order custom-sized sheets from certified suppliers.
High-impact zones (e.g., workshops with flying debris).
UV-exposed areas (windows, sunlit rooms).
Ultrafast/high-peak-power lasers (risk of nonlinear damage).
Unmonitored environments (no regular OD checks).
No! It is wavelength-specific. Always:
Match the sheet to your laser’s exact wavelength (e.g., 1064 nm, 10.6 µm).
Verify its OD rating meets your laser’s power/energy (per standards like EN 207, ANSI Z136).
Unprotected: OD degrades significantly in 1–5 years if exposed to UV.
UV-stabilized: Specialized sheets last 10+ years (verify with manufacturer testing).
Always monitor: Replace if scratches, cracks, or discoloration appear.
⚠️ Brittleness: Shatters on impact → not suitable for high-risk industrial environments.
Optical clarity: Superior light transmission vs. polycarbonate.
Scratch resistance: Harder surface resists daily wear.
Cost-effective: 30–50% cheaper than polycarbonate.
Lightweight: Ideal for portable enclosures or eyewear.
A: A transparent acrylic (PMMA) sheet infused with wavelength-specific dyes or absorbers to block laser radiation. It’s engineered to achieve a specific Optical Density (OD) to protect users from laser exposure.
