Product Description Product Description Fiber Laser Protective Windows The role of a fiber laser protective lens is to safeguard the critical optical components in fiber laser systems. It prevents contaminants like metal debris, dust, and smoke from reaching the internal optics, which helps avoid damage and degradation to the laser system's focusing lens. By acting as a barrier, the protective lens enhances the longevity and reliability of the fiber laser, ensuring consistent performance and maintaining high cutting or welding precision.Additionally, these protective lenses are designed to withstand high temperatures and have excellent optical clarity, which minimizes any impact on the laser beam's quality. This reduces maintenance needs and helps lower operational costs, making them essential for applications in precise laser cutting and welding.Commonly used brands for laser cutting heads include RayTools, WSX, Precitec, Bodor, and OSPRI. These brands offer a range of high-quality cutting heads compatible with various laser systems, providing precision and durability in applications like metal cutting and welding.Type: Dia 18-160mmMaterial: Fused Silica(Quartz )Wavelength: 1064nmTransmittance: 99.5%Model: 30*130*1.530*230*330*430*530*5 6KW30*5 15KW30*5(Gap)32*232*5 8KW32*6.35 15KW34*1.5 15KW34*334*5 8KW34*5 15KW34*5 20KW34*5 30KWIf you have any questions about the products or shipping,please contact our customer service.Detailed PhotosFAQFAQ - Frequently Asked Questions About Laser Cutting Head Protective Lenses1. Which laser cutting head brands are these protective lenses compatible with?Our lenses are compatible with many mainstream laser cutting head brands, including Precitec, Raytools, WSX, BT240S, QBH, and more. Please confirm the model before ordering or contact our support team for assistance.2. What specifications and materials are available?Common diameters include ?18mm, ?20mm, ?24mm, ?27.9mm, etc., with typical thicknesses of 1.5mm or 2.0mm. Materials include quartz and coated glass, offering high heat resistance and excellent anti-reflection performance.3. What type of coating do the lenses have?We offer lenses with single-sided AR (anti-reflection) or double-sided AR coatings to reduce laser loss and extend service life.4. When should I replace the protective lens?If you notice a drop in cutting performance, focal point shift, burns, scratches, or contamination on the lens, it's time to replace it to protect the focusing lens and cutting head.5. Are the lenses easy to install?Yes, installation is simple. Most cutting heads have standard lens slots. Please wear cleanroom gloves when replacing to avoid contamination.6. Can the protective lenses be reused?We do not recommend reusing contaminated or scratched lenses. Improper cleaning may also damage them. For best results, use a new protective lens each time.7. How should I store unused lenses?Store them in a dry, dust-free, anti-static package, away from direct sunlight and sudden temperature changes to prevent coating degradation or contamination.8. Do you support custom sizes or bulk orders?Yes, we support OEM/ODM customization and bulk purchases. Please contact us for a quotation and lead time.9. How do you arrange shipping and delivery?We stock common sizes and ship within 24 hours. Multiple international shipping options are available, such as DHL, FedEx, and UPS.10. Is there a warranty or return policy for the lenses?Since protective lenses are consumables, returns or exchanges are not accepted once opened or used. If any damage occurs during transit, please contact us within 48 hours, and we'll assist you with after-sales service.
