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.

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.

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.

Is there a warranty or return policy for the lenses?

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with manufacturing, technical services, electronic and electromechanical component activities, and metal cutting and welding equipment activities. It provides broad customization, 3D design, ODM, and OEM services, and has introduced new products during the past year. Quality management includes two inspectors, documented inspection instructions, and a documented warehouse control process, but no quality-control test equipment is reported. The supplier has inventory and overseas warehouse capabilities, while no overseas showroom is available. Service governance is incomplete: supplier-service assessment has records but no written procedure, and no written corrective-action or customer-complaint procedures or records are reported. Evidence is insufficient for certification holding, after-sales capability, and customer cases.

Supplier typeThe supplier is explicitly classified as a trading company, while its stated business scope also includes manufacturing, sales of electronic and electromechanical components, metal cutting and welding equipment, equipment installation, maintenance, and technical services. This indicates a trading-led supplier with broad related manufacturing and service activities.

R&D capabilityThe supplier identifies itself as a professional technical supplier, provides 3D software design, has one R&D engineer responsible for customer-request confirmation, new-product design, and technical support, and reports new products during the past year plus ODM services. It does not have an available SDK, but the documented product-development and design activities support an innovation capability assessment.

Production capacityThe supplier’s scope includes manufacturing and equipment-related production activities; it has two quality-control staff, documented warehouse control, documented finished-product inspection instructions, inventory capability, and overseas warehouse capability. However, no quality-control test equipment is reported and manufacturing-capacity contract status is unknown, so production capability is supported but not fully evidenced.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, flexible customization, and 3D software design services. Its ODM and OEM capabilities further support the ability to deliver customized products and designs.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of brand customer experience. No customer names, project details, volumes, or verification records are provided, so the breadth and strength of customer cases cannot be determined.

Product Q&A

Q: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.

Q: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.

Q: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.

Q: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.

Q: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.
