Polished with edging N-BK7/K9 optical windows /sheet for night vision and laser machine
N-BK7 is a RoHS-compliant borosilicate crown glass. It has excellent transmission in the visible and near IR portions of the spectrum (350 nm - 2.0 µm). N-BK7 is probably the most common optical glass used in high-quality optical components. N-BK7 is a hard glass that can withstand a variety of physical and chemical stressors. It is relatively scratch and chemical resistant. It also has a low bubble and inclusion content, making it a useful glass for precision lenses. The index of refraction of N-BK7 is 1.517 at 587.6 nm.
