FAQ

Q: Can you send me free samples or Can i have an sample order?

A: Yes, We accept sample orders, and we're also willing to send you free sample to test and check its quality . if we don't have the item in stock , then you could place an sample order.

Q: How many days can i get my package after placing order?

A: If the order needs customized also the quantity is big. it will take around 10-30 wroking days to produce then shipping.

Q: OEM services available?

A: Sure, please send us your design paper on platform to confirm more details information.

Q: What shipping methods do you have?

A: For small quanities or sample could by express such as: Fedex, UPS, DHL, EMS, etc. Large scale quantity in your demands:by sea/train ,or by air.In your requests.

Q: What is the difference between Quartz Laser Protective Lens and regular glass laser windows?

A: Quartz offers higher thermal resistance, better UV transmission, and a much higher laser damage threshold compared to standard optical glass.

Q: Are custom sizes and coatings available?

A: Absolutely! We provide custom dimensions, thicknesses, and coatings (AR, HR, partial reflection) upon request.

Q: How should I clean the Quartz Laser Protective Lens?

A: Use a mild solvent (isopropyl alcohol) and a lint-free cloth. Avoid abrasive cleaners.

Q: What is the typical lifespan of these windows?

A: Depending on usage, they can last years under normal conditions. High-power lasers may require periodic inspection/replacement.
