It is supplied with a surface quality rating of 40-20 scratch-dig and a flatness of 1/10 λ measured at 633 nm. The manufacturer offers sizes from 3 mm up to 280 mm in diameter, covering a broad range of optical dimensions. Its spectral transmittance extends from 250 nm in the ultraviolet to 7 µm in the mid‑infrared.
Calcium fluoride is valued for its low absorption coefficient and high laser damage threshold, making it suitable for high‑energy laser applications. The material typically exhibits a refractive index of about 1.433 at the D‑line and a density of 3.18 g cm‑3. In many systems the window can be used uncoated because its intrinsic transmission already meets demanding performance criteria.
Typical buyers include OEMs of excimer laser systems, research laboratories and manufacturers of prisms and precision lenses. When sourcing, buyers should confirm the minimum order quantity, packaging format and the Incoterm that will be applied. The supplier’s harbour verification tier indicates a basic level of trust, but trade terms such as payment method and lead time must be agreed directly with the company.

Before placing an order, importers should verify that the window material is genuine calcium fluoride and that the supplied surface quality and flatness match the 40-20 and 1/10 λ specifications. Request the supplier’s test reports for transmittance across the 250 nm‑7 µm band and for dimensional inspection. Confirm the exact diameter tolerance and any coating requirements, even if the product is intended to be used uncoated.
Logistics planning should include confirmation of the packaging style - typically bulk cushioned cartons with foam inserts - and the quantity per carton. Ask the supplier for an estimated lead time based on the required order size, and negotiate the preferred Incoterm, such as FOB Shanghai or CIF Shanghai, according to your shipping strategy. Payment terms are usually negotiable; common arrangements are a 30 % advance by T/T followed by a balance against a copy of the Bill of Lading.
Quality assurance can be reinforced by arranging a third‑party inspection before shipment, focusing on surface defect count, flatness measurement and dimensional accuracy. Request a Certificate of Conformity and, if needed, a Material Safety Data Sheet for calcium fluoride handling. Retain all inspection reports and certificates as part of the import documentation to satisfy customs and end‑user requirements.
