Laser Safety Viewing Window UV IR Filter 190–2000nm CE | Leeyongin

Leeyongin Laser Safety Viewing Window — CE-Certified Protective Filter Panel

Protect your workspace and equipment with the Leeyongin Laser Safety Viewing Window — a precision-engineered protective filter panel designed for professional laser environments. Whether you're operating cutting, welding, engraving, or research-grade laser systems, this CE-certified safety window reliably attenuates harmful laser radiation across UV, visible, and IR wavelengths, keeping operators and bystanders secure.

Made in Mainland China.

Why Laser Viewing Safety Matters

Even brief, accidental exposure to a direct or reflected laser beam can cause irreversible damage to optical instruments and sensitive equipment. The key measure of potential harm is irradiance — power per unit area (W/cm²). A properly rated safety window intercepts and attenuates the beam before it reaches unprotected areas, making it an essential barrier in any professional laser setup.

Available Filter Options

• Option 1: OD4+ @ 190–480 nm | VLT ≤ 25% — ideal for UV and short-wavelength visible lasers (e.g., 355 nm, 405 nm, 450 nm)
• Option 2: OD5+ @ 190–540 nm | VLT ≤ 25% — enhanced attenuation for UV through green lasers (e.g., 532 nm)
• Option 3: OD4+ @ 900–2000 nm | VLT ≤ 35% — tailored for near-IR and IR lasers (e.g., 1064 nm, 1550 nm)
• Option 4: OD5+ @ 190–480 nm & 900–2000 nm | VLT ≤ 35% — dual-band protection covering both UV/visible and IR ranges

Not Sure Which Wavelength Option to Choose?

Selecting the correct protection wavelength is critical. We strongly recommend ordering a small test sample first to confirm suitability before purchasing a full-sized panel. Please contact us directly for expert guidance or to request a sample.

Frequently Asked Questions

Q: What does OD (Optical Density) mean for a laser safety window?

A: Optical Density (OD) is a logarithmic measure of how much a filter attenuates a laser beam. An OD4 rating means the filter reduces the laser's intensity by a factor of 10,000 (10⁴), while OD5 reduces it by a factor of 100,000 (10⁵). Higher OD values indicate stronger laser beam attenuation and greater protection for operators and equipment.

Q: Can this laser safety viewing window be used for 532 nm and 1064 nm lasers?

A: Yes. Option 2 (OD5+ @ 190–540 nm) covers 532 nm green lasers, and Option 3 (OD4+ @ 900–2000 nm) covers 1064 nm Nd:YAG lasers. For dual-band coverage of both wavelengths in a single panel, Option 4 (OD5+ @ 190–480 nm & 900–2000 nm) provides comprehensive protection across both UV/visible and near-IR ranges.

Q: Is this laser safety window CE certified?

A: Yes. All Leeyongin laser safety viewing windows carry CE certification, confirming compliance with applicable European safety standards for laser protective equipment and optical radiation filters.

Q: Can I order a custom size for my laser enclosure or machine?

A: Absolutely. While several standard sizes are available (ranging from 250×360 mm up to 500×250 mm with 2–5 mm thickness), custom dimensions can be produced upon request. Please contact us with your specific measurements and we will provide a tailored solution.

Q: Should I order a sample before buying a full-sized panel?

A: We strongly recommend it, especially if you are unsure which wavelength range best suits your laser system. Ordering a small test sample first allows you to verify filter performance and compatibility before committing to a full-size panel purchase.
