Frequently Asked Questions

Everything you need to know about our fiber laser protective windows.

What is the difference between JGS1 and JGS2 fused silica?
JGS1 (UV grade fused silica) is highly transparent in the ultraviolet and visible regions and has no absorption bands, making it ideal for high-power fiber lasers (up to 30kW+). JGS2 (Optical grade fused silica) is more suitable for standard or lower power applications. We predominantly supply JGS1 for protective windows to ensure maximum durability and laser transmission.
Are your lenses compatible with Raytools, Precitec, or WSX laser heads?
Yes, absolutely. As a source factory, we manufacture protective windows strictly according to the standard dimensions of all major global laser head brands, including Raytools, Precitec, WSX, Bodor, Bystronic, and Highyag. If you are unsure of the size, simply send us the brand and model of your laser head, and our engineers will match the correct lens for you.
How often should I replace the protective window?
The lifespan depends on your working environment and laser power. Typically, a high-quality protective window can last from a few weeks to a few months. You should replace it immediately if you notice black spots, burning marks, or a significant drop in cutting/welding efficiency, as a damaged window can lead to internal contamination of the laser head.
What is the Minimum Order Quantity (MOQ) for wholesale?
For standard sizes in stock, our MOQ is very flexible—usually starting from 10 pieces. For custom specifications (special thickness, diameter, or non-standard AR coating), the MOQ is generally 50-100 pieces depending on the complexity. We offer tiered bulk discounts for larger orders.
Can I request customized dimensions or coatings?
Yes. We provide comprehensive OEM/ODM services. Our optical processing center can customize lens diameters ranging from 10mm to 150mm, with various AR (Anti-Reflective) coatings optimized for different wavelengths (e.g., 1064nm, 1070nm). Contact us with your technical drawings or requirements.
