China Wholesale Fused Silica Sheet Factories & Exporter for the Espoo Market

Selection depends on the operating wavelength. Choose JGS1 (synthetic silica) if your application involves deep-UV optics, excimer laser processing, or fluorescence analysis down to 185 nm, as it is bubble-free and free of metallic impurities. JGS2 is suited for standard UV-Visible instrumentation and sight glasses (220–2500 nm). For IR heaters, pyrometry, and thermal windows where the 2.73 µm water absorption band must be eliminated, specify water-free JGS3 (<5 ppm OH).

Using precision diamond wire slicing and CNC machining centers, we routinely hold length and width tolerances within ±0.05 mm, and thickness tolerances down to ±0.02 mm for precision optical plates. Standard mechanical plates are produced at ±0.1 mm to ±0.2 mm. Surface flatness can be controlled down to λ/4 or λ/10 per 25 mm diameter upon request.

For standard quartz sheets, tubes, and catalog infrared heating lamps, our MOQ is flexible, starting from 8 to 10 pieces to support prototype testing and pilot lines. Custom machined sheets generally require a 10–20 piece trial run depending on geometry. Sampling lead time is typically 5 to 7 days, with bulk production completed in 12 to 18 business days.

We use a multi-tiered engineered packing protocol. Each sheet is individually wrapped in cleanroom dust-free static-shielding film, placed between high-density expanded polyethylene (EPE) shock dampeners, vacuum-sealed into rigid inner cartons, and suspended inside heavy-duty, fumigated export plywood cases. We maintain a zero-breakage track record across our European export routes.

Yes. With over a decade of OEM engineering expertise, we routinely reverse-engineer heating elements. By supplying high-resolution photographs of the terminal caps, end markings, tube profile measurements (single or twin tube dimensions), and electrical parameters (voltage/wattage), our engineering department can recreate factory-matching replacements.

We support standard international trade terms including FOB Shanghai/Qingdao, CIF Helsinki, and DDP (Delivered Duty Paid) directly to your facility in Espoo, Vantaa, or greater Helsinki. All shipments include complete commercial invoices, packing lists, certificates of material conformity (CoC), and RoHS/REACH declaration sheets to streamline Finnish Customs (Tulli) clearance.
