Fused Silica Window Dia.50mm
The Fused Silica Window with a 50 mm clear aperture is supplied by Changchun Sunday Optoelectronics Co., Ltd in China. The component is manufactured from fused silica (SiO₂) and meets a surface quality of 10‑5 with a flatness of 1/10 λ. Diameter tolerance is controlled to ±0.02 mm, ensuring tight integration in precision optical assemblies. The window is offered also in alternative substrates such as BK7, sapphire, ZnS₂, CaF₂, Si and Ge.
Fused silica provides excellent transmission across the UV to IR spectrum and resists thermal shock, making it a standard choice for laser delivery and semiconductor inspection. Typical industry practice adds a beveled edge and optional anti‑reflective coating to reduce stray reflections. The material’s low coefficient of thermal expansion supports stable performance in demanding scientific equipment.
Buyers such as photonics manufacturers, semiconductor fab facilities and research laboratories source these windows for spectroscopy, defense optics and medical laser devices. Trade is prepared for bulk orders, with packaging in clean‑room compatible carriers; specific MOQ and lead‑time are not disclosed in the listing and should be confirmed with the supplier. Payment and Incoterms are negotiable per order.

Sourcing Fused Silica Window Dia.50mm from Changchun Sunday Optoelectronics Co., Ltd - China Import Guide
Before placing an order, confirm the exact substrate material and surface grade required for your system. Request a certified material test report that lists SiO₂ purity, surface roughness and flatness measurements. Verify that the diameter tolerance of ±0.02 mm aligns with your mechanical mounting tolerances.
Discuss the preferred Incoterm - FOB, CIF or DDP - and ensure the supplier can handle the packaging needed for clean‑room transport. Lead‑time is not published, so ask for a production schedule that fits your project timeline. Payment terms such as a letter of credit or advance payment should be agreed in writing.
Arrange for a third‑party inspection at the factory or upon arrival to verify surface quality and coating integrity. Request a full inspection certificate that includes visual inspection, interferometric flatness test and coating spectral data. Maintaining these documents will facilitate customs clearance and downstream quality assurance.
