Technical Parameters and Core Advantages
The operational stability and processing accuracy of fiber laser equipment are highly dependent on the performance of protective windows, which undertake the critical task of protecting core optical systems and stabilizing laser transmission. This high-performance fused silica protective window stands out in the industry with premium material configuration, precise technical parameters and mature optical coating technology, providing reliable full-cycle protection for industrial fiber laser processing equipment.
In terms of base material, the product adopts imported JGS1 fused silica, a high-end optical material exclusively suitable for fiber laser working conditions, which is fundamentally superior to ordinary glass and ordinary quartz materials. The JGS1 fused silica substrate boasts ultra-high optical purity, extremely low internal impurity content, and no bubbles, stripes or optical defects, achieving excellent optical uniformity. This feature enables the window sheet to support high-purity laser transmission without causing light scattering or distortion, fully matching the transmission requirements of mainstream fiber lasers. In addition, the material has an ultra-low thermal expansion coefficient and outstanding thermal shock resistance. It can continuously withstand high-temperature radiation and intense energy impact generated by long-term laser operation, avoiding common problems such as lens deformation, cracking, yellowing and light attenuation. The excellent high-temperature resistance and structural stability greatly extend the service life of the protective window, effectively reducing the frequent replacement of accessories and production downtime losses caused by component failure.
In terms of dimensional specifications, this protective window realizes full coverage of mainstream industrial specifications with strong universality and adaptability. The diameter ranges from 18mm to 134mm and the thickness ranges from 2mm to 7mm, covering the specification requirements of small precision laser marking equipment, medium laser welding equipment and large industrial laser cutting equipment of various brands. Adopting high-precision flat window molding technology, the product has ultra-high surface flatness and finish without scratches, pitting and surface defects. The standardized and precise dimensional design ensures seamless assembly with laser equipment, while the flat and smooth optical surface guarantees vertical and stable laser light path transmission, preventing laser energy offset and processing accuracy reduction caused by lens deformation and surface flaws, and maintaining consistent high-precision processing effects for a long time.
Optical coating technology is the core technical highlight of this product. The window sheet adopts double-sided AR/AR anti-reflection coating process, with a precise coating band of 1030-1090nm, which is perfectly matched with the working band of commercial fiber lasers. Processed by high-precision vacuum coating equipment, the double-sided anti-reflection film has uniform thickness, strong adhesion, excellent friction resistance and peeling resistance, with stable performance in long-term continuous industrial working conditions. The high-quality anti-reflection coating can effectively reduce the surface reflection rate of the lens, greatly improve laser light transmittance, minimize light path energy loss, and maximize the utilization rate of laser energy acting on the workpiece, thereby significantly improving the efficiency and quality of laser cutting, welding and marking processing. Meanwhile, the targeted band coating design can effectively filter stray light and suppress reflected light backflow, avoid damage to laser light sources and internal core lenses caused by reflected laser, and further optimize the stability of the entire laser light path system.
Benefiting from premium materials and sophisticated craftsmanship, the product has comprehensive core application advantages. It features ultra-high laser damage threshold, which can resist laser energy impact, high-temperature burning, dust friction and multiple external damages, maintaining stable optical performance for a long time. As an indispensable protective barrier for laser equipment, it can effectively isolate metal spatter, molten slag splashing, dust particles, smoke impurities and other pollutants generated during laser processing, fundamentally preventing core optical lenses from contamination, scratching and corrosion, and avoiding processing defects such as light path failure and spot distortion. Compared with ordinary glass and inferior quartz protective sheets, this product has far better weather resistance and aging resistance, adapting to high-strength and continuous industrial processing environments. Its long service life and low failure rate greatly reduce equipment operation and maintenance costs, improve overall production efficiency, and is a high-cost-performance and high-reliability supporting accessory for modern fiber laser equipment.
FAQ
Q: How to Install the machine?
A: After receive our machine, customers do not need to install it and can use it directly.
Q: How to operate the machine? is training necessary?
A: The machine is mainly controlled by software. It’s very easy, not complicated. Before shipment, we will make a simple operation manual with pictures and provide user manual of software. Generally speaking, an operator, who is not familiar with fiber laser marking machine before can still operate it very well. According to customers’ requests, we can send our technician to customer’ plant for machine training or customers can come to our plant for machine training if needed.
Q: In case machine exists problem, how to do after sales service?
A: We provide two years machine warranty. During the 1 year warranty, in case machine exists problem, we will provide parts required with free of charge by express. But as for the parts damaged by artificially, it does not fall within our warranty list. After the warranty, we still provide lifetime service.
Q: What’s delivery time?
Q: What’s delivery time?
A: Generally speaking, lead time is 5-7 working days after receive the payment.
Q: Can we add a protection cover?
A: Yes, we can add a protection cover if you need. We can customize the design as customers’ requests.
