Laser Safety Filter Windows 190–2000nm UV IR Shield | CE Certified
Laser Safety Filter Windows 190–2000nm UV IR Shield | CE Certified
LEEYONGIN Laser Safety Filter Windows – CE Certified Protection for Industrial & Scientific Applications
Designed for professionals working with high-powered laser systems, the LEEYONGIN Laser Safety Filter Windows provide reliable optical shielding across a broad spectrum of wavelengths — from UV (190nm) through visible and into near-infrared (up to 2000nm). Whether you're operating a cutting laser, engraving system, or scientific instrument, these precision-engineered filter windows help safeguard both equipment and operators from accidental beam exposure.
Made in Mainland China.
Why Laser Safety Filtering Matters
Even brief, accidental exposure to a direct or reflected laser beam can cause irreversible damage to optical systems and equipment — and to human eyes — depending on wavelength, output power, and exposure duration. A critical measure of a filter's protective capability is its Optical Density (OD), which indicates how many orders of magnitude the laser intensity is reduced. These windows are engineered to meet rigorous CE safety standards, giving you confidence in every installation.

Frequently Asked Questions
Q: What does OD (Optical Density) mean for a laser safety filter window?
A: Optical Density (OD) indicates how effectively the filter window attenuates laser beam intensity. An OD of 4 reduces the transmitted laser power by a factor of 10,000 (10⁴), while an OD of 5 reduces it by a factor of 100,000 (10⁵). Higher OD values provide greater beam attenuation, making OD5+ windows suitable for higher-power laser systems.
Q: Can I use this laser safety filter window for both 1064nm and 532nm lasers?
A: Yes — select the appropriate SKU based on your laser's wavelength. For 532nm (green, visible), choose S2 (190–540nm) or S5/S6 for larger panels. For 1064nm (near-IR), choose S3 (900–2000nm) or S4/S6 for combined UV-IR coverage. If you're unsure, contact us with your laser specs and we'll recommend the correct filter.
Q: Is a sample available before I purchase a large-sized laser safety window?
A: Absolutely. We offer small 90×90×3mm sample pieces (SKUs S1–S4) specifically for testing and evaluation. This allows you to verify wavelength compatibility and optical performance before ordering a full-size or custom-dimension window.
Q: Are custom sizes available for industrial laser enclosures?
A: Yes. In addition to our standard sizes (ranging from 250×250mm up to 400×500mm), we offer custom-cut laser safety filter windows to fit your specific enclosure or system dimensions. Please contact us with your exact measurements and wavelength requirements.
Q: What certifications do these laser safety windows carry?
A: These laser safety filter windows are CE certified, meeting European safety and quality standards for laser protective equipment used in industrial and technical environments.
