FAQ
Q1: 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.
Q2: Are custom sizes and coatings available?
A: Absolutely! We provide custom dimensions, thicknesses, and coatings (AR, HR, partial reflection) upon request.
Q3: How should I clean the Quartz Laser Protective Lens?
A: Use a mild solvent (isopropyl alcohol) and a lint-free cloth. Avoid abrasive cleaners.
Q4: 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.
Q5: Do you offer OEM/ODM services?
A: Yes, we work with clients to develop bespoke laser protection solutions.
