FAQ
Can you produce non-standard custom sizes?
Yes. We process quartz plates strictly according to customer drawings, including special outlines, through holes, chamfers and surface coating requirements.
What optical coatings are available?
We offer single-layer and multi-layer AR anti-reflection coatings matching UV, visible and infrared working bands.
What is your typical lead time?
Samples: 7–12 working days; mass production orders: 15–25 working days based on quantity and processing complexity.
