The Crystal Optics Caf2 Window with a 12.7 mm diameter is manufactured by Changchun Sunday Optoelectronics Co., Ltd in Changchun, China. It is fabricated from high‑purity calcium fluoride (CaF₂), a material renowned for low dispersion and high transmission from the ultraviolet (250 nm) to the mid‑infrared (7 µm) spectral regions. The supplier lists the component as an optical window designed for precision applications, with a polished surface and a nominal thickness that matches the 12.7 mm aperture. Typical calcium fluoride windows of this size exhibit a refractive index of approximately 1.4338 at 589 nm and a bulk transmission exceeding 95 % across the stated range. Industry practice often specifies surface flatness of λ/10 (at 632.8 nm) and a scratch‑dig quality of 60‑40, which can be requested from the manufacturer. Many users apply an anti‑reflection coating tuned to the 3 µm region; such a coating is standard for CaF₂ windows but must be confirmed for each batch. The material’s resistance to thermal shock and chemical corrosion makes it suitable for environments with rapid temperature changes. Typical wedge angle tolerance for precision windows is less than 10 arcseconds, ensuring beam deviation remains negligible. Buyers such as research laboratories, telecommunications equipment manufacturers and industrial laser system integrators frequently source this component. The listing mentions flexible minimum order quantities and offers CIF or FOB shipping, but the exact MOQ should be verified directly with Changchun Sunday Optoelectronics. Prospective importers are advised to confirm the Incoterm, required documentation and preferred payment method before finalising the purchase.

Before committing to a purchase of the 12.7 mm CaF₂ window, importers should obtain the mill test report that details transmission, refractive index and surface flatness. Confirm whether an anti‑reflection coating is applied and request the coating performance sheet. Verify the supplied dimensions and tolerance certificates, and if possible, arrange a third‑party optical audit to ensure the component meets the stated specifications.
Changchun Sunday Optoelectronics indicates that shipments can be arranged on CIF or FOB terms, but the exact Incoterm must be agreed in the sales contract. Lead time is not disclosed in the listing; therefore, ask the supplier for the expected production and dispatch schedule. Typical payment methods include T/T against a confirmed letter of credit; confirm any advance deposit and the currency to be used.
Quality assurance for optical windows relies on visual inspection for surface defects and interferometric testing for flatness. Arrange a pre‑shipment inspection by a qualified optical metrology lab to verify λ/10 flatness and 60‑40 scratch‑dig quality. Request the certificate of conformity, coating data sheet and any relevant ISO or RoHS declarations. Maintaining a clear communication channel with the supplier will help resolve any non‑conformities prior to loading.
