OPTICAL ACRYLIC EXPERT

532nm Laser Safety Windows | Blocks 190–540nm UV & Green Lasers | Strong Absorption of 10.6 μm CO₂ Lasers

CT-532 Core Protective Range

  • 190–540nm Full Spectrum Protection
    → 190–535nm achieves OD5+
    → Effectively blocks UV (193nm, 248nm), blue light (355nm, 445nm), and green lasers (532nm Nd:YAG)

  • 532nm (Nd:YAG Green Laser): OD6+
    → High-efficiency protection against the most common industrial and medical green lasers

  • 600–1100nm: High Transmission >80%
    → Ensures clear visibility during laser operation and monitoring

  • 10.6 μm (CO₂ Laser): OD5+
    → Naturally absorbed by the material’s molecular structure in the mid-infrared range, providing effective protection for CO₂ laser cutting and engraving systems

We are the only manufacturer in Taiwan producing laser protection acrylic filters in-house. Unlike resellers of imports, we control formulation and casting, use optical-grade PMMA, and provide verified spectral performance across 190–540 nm and 10.6 μm CO₂. This means stable quality, faster lead times, and flexible customization.

Broad protection from UV-C / UV-B / UV-A through visible blue (≈400–500 nm) and green (500–540 nm, incl. 532 nm Nd:YAG), plus strong absorption at 10.6 μm CO₂. Outside the blocked bands, visible transmission remains high for clear observation.

Yes. Each grade comes with in-house spectrophotometric data (OD curves) and can be supported by international third-party certifications (e.g., SGS, UL) upon request.

The required OD depends on wavelength, output power, and application. Share your laser model and usage (e.g., cutting, marking, medical), and our technical team will recommend an OD that balances safety and visibility.

Some 532 nm DPSS systems emit residual IR (e.g., 1064 nm). Our panels are designed to consider multi-band risks and can be specified to block both visible green and IR leakage where required.

We offer precision cutting up to 1220 × 2440 mm, with tailored OD levels, thicknesses, and mounting options to suit labs, industrial enclosures, and medical systems.

With optical-grade PMMA, our panels maintain high visible transmission (>80% in 600–1100 nm) for clear viewing. They also offer excellent chemical stability and surface hardness suitable for daily operation.
