Product Description

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.

Yutai Optics provides domes from glass, quartz, depending on the temperature, shock and scratch resistance required. These items
will be manufactured on customer request only.We recommend thickness at least 4mm for customer as production cost will be better
than the thinner ones.
