DIA12.7mm BK7 BI-CONCAVE LENSES AR@600-1100nm

BK7 (or N-BK7, a lead-free version) is a very common type of borosilicate crown glass. It’s a popular choice for commercial optics due to its Excellent optical properties, Broad transmission range, Good physical properties: It is relatively hard and resistant to scratches, and it’s chemically stable.

An anti-reflection (AR) coating is a thin film applied to the lens surfaces to minimize light loss due to reflection. Whenever light passes from one medium to another (like from air into glass), a portion of it is reflected at the interface. This can lead to reduced system efficiency, “ghost” images, and even damage in high-power laser systems.
