Sapphire Window BBAR (1650-3000nm) Coated
The product is a synthetic sapphire optical window that carries a broadband anti‑reflection (BBAR) coating designed for the 1650‑3000 nm infrared range. Changchun Sunday Optoelectronics offers diameters from 2 mm up to 600 mm, each held to a tolerance of ±0.02 mm. The windows are specified as optical‑grade Al₂O₃ with a surface quality class of 60‑40 and a flatness of 1/10 λ. A 0.25 mm × 45° chamfer is machined on the edge, and the AR coating is applied on request.
Synthetic sapphire of this grade is commonly used in high‑precision infrared spectroscopy because of its low absorption and excellent thermal stability. The ±0.02 mm diameter tolerance and 1/10 λ flatness meet typical industry requirements for laser‑system windows and aerospace sensors. Standard BBAR coatings aim for reflectance below 0.5 % across the target band, which aligns with the supplier’s description. The material’s hardness of 9 on the Mohs scale provides durability against mechanical wear.
These windows are suited for infrared spectrometers, thermal‑imaging cameras, defence‑grade laser assemblies and other scientific instruments that demand high transmission and mechanical robustness. Buyers such as OEMs, research laboratories and system integrators typically request FOB or CIF terms and will confirm lead times directly with the factory. The supplier’s profile shows a harbour‑level trust tier but no published response rate, so importers should verify contact responsiveness and request a formal quotation before placing an order.

Sourcing Sapphire Window BBAR (1650-3000nm) Coated from Changchun Sunday Optoelectronics Co., Ltd - China Import Guide
Before placing an order, importers should ask the supplier for a sample window with the requested diameter and coating, together with the interferometric flatness report and transmission spectrum. Verifying the coating wavelength range and confirming the 60‑40 surface quality through a third‑party inspection will reduce the risk of receiving non‑conforming parts.
Typical lead times for custom‑coated sapphire windows range from four to eight weeks, but the exact schedule must be confirmed with Changchun Sunday Optoelectronics. Buyers usually negotiate FOB or CIF terms, and should clarify the port of loading in China, insurance coverage and any pre‑payment requirements before signing a contract.
During the sourcing process, arrange an independent quality audit that checks the material grade, dimensional tolerances and coating performance. Request the supplier’s test certificates for optical grade, flatness and AR coating reflectance, and ensure these documents are included in the commercial invoice and packing list for customs clearance.
