High Precison N-BK7 Window 150*10mm
The High Precison N‑BK7 Window measures 150 mm in diameter and 10 mm thick. It is fabricated from N‑BK7 borosilicate crown glass, a Schott‑grade material widely used in laser and scientific optics. The glass offers a transmission window from 350 nm to 2000 nm, with low bubble and inclusion content. This product is listed by Changchun Sunday Optoelectronics Co., Ltd, based in Changchun, China.
N‑BK7 provides a refractive index of 1.5168 at 587.6 nm and a typical surface quality of 10‑10 scratch‑dig, meeting λ/10 flatness over the clear aperture. Standard industry tolerances for this size are diameter deviation within ±0.05 mm and thickness uniformity within ±0.02 mm. The supplier notes the use of four‑axis polishing and large‑size ring polishing machines to achieve these tolerances. Typical packaging includes a protective polymer film and a wooden crate to prevent damage during transport.
The window is suited for precision imaging systems, laser delivery modules, and defence‑grade instrumentation. Buyers such as research labs, medical device manufacturers, and OEMs in aerospace commonly source this component. Trade discussions should confirm the minimum order quantity, incoterm (FOB or CIF), and any required test certificates before placing an order.

Sourcing High Precison N-BK7 Window 150*10mm from Changchurn Sunday Optoelectronics Co., Ltd - China Import Guide
Before ordering, verify that the glass grade, dimensions and surface quality match the specifications required for your system. Request the material test certificate and a recent inspection report to confirm compliance with Schott N‑BK7 standards. Also confirm the packaging method will protect the window during transit and that any handling instructions are clearly communicated.
Logistics should be clarified early: agree on an incoterm such as FOB at the Changchun port or CIF to a destination port, and ask the supplier for an estimated lead time based on the order size. Payment terms are typically negotiated on a T/T basis, but confirm any letters of credit or escrow arrangements before finalising the contract. Ensure that freight forwarder details are shared so that customs documentation can be prepared in advance.
Upon receipt, arrange a visual inspection for surface defects and verify the flatness and scratch‑dig ratings with a qualified metrology lab. Conduct a pressure test at the rated 27.6 MPa to confirm integrity, and retain the test certificate for quality records. Maintaining a clear chain of documentation - from material certification through final inspection - helps streamline customs clearance and downstream integration.
