H-bak7, Ge, Znse, Bk7 , Sapphire Windows
The product is a fused silica optical window offered in diameters ranging from 2 mm to 300 mm. Each blank meets a surface figure of 1/10633 λ and a diameter tolerance of +0.0 / -0.15 mm. Thickness tolerance is ±0.1 mm and parallelism is achieved on 90% of the surfaces. The bevel is machined to 0.25 mm at a 45° angle and coating is supplied according to customer specifications.
Fused silica provides excellent transmission in the ultraviolet to near‑infrared spectrum and a low thermal expansion coefficient, making it a standard material for high‑precision optics. Typical industry practice limits scratch‑dig performance to 60‑40 or better, which aligns with the listed surface quality. The windows can be supplied with anti‑reflective or protective coatings, a common requirement for laser and imaging systems. Suppliers often quote a typical transmission of 99% in the visible range for this grade of material.
These windows are used by manufacturers of laser equipment, scientific instrumentation and aerospace optics, where dimensional stability is critical. Importers should request a test certificate confirming surface figure and coating performance before placing a bulk order. Because the listing does not state minimum order quantity, lead time or price, the buyer must confirm those details directly with the supplier.

Sourcing H-bak7, Ge, Znse, Bk7 , Sapphire Windows from Changchun Yutai Optics Co., Ltd. - China Import Guide
Before placing an order, verify the exact diameter, thickness and coating specifications required for your end‑use. Request a sample or a detailed data sheet that includes surface figure, parallelism and scratch‑dig measurements. Confirm that the supplier can meet any regulatory or export documentation needed for optical components.
Import logistics for China‑origin optical windows typically involve air freight for small batches or sea freight for larger volumes. Clarify the preferred Incoterm, such as FOB or CIF, and confirm the payment terms, which are often negotiated as a letter of credit for first‑time buyers. Lead time and packaging details should be obtained directly from the supplier.
Quality assurance is essential for high‑precision optics. Arrange for an independent inspection agency to verify surface figure, coating performance and dimensional tolerances upon arrival. Request the supplier’s test certificates and consider a post‑delivery audit to ensure compliance with your quality standards.
