KBX163 50.8 mm Dia. x 175 mm FL; Uncoated; Double-Convex Lens
The KBX163 is a high-quality, double-convex lens offered by MKS/Newport. This lens, which features a Schott N-BK7 material ID, is designed with a base shape of a circle and a spherical geometry. The lens has a diameter of 50.8 mm and a thickness at the edge of 3 mm, while its center thickness measures 6.607 mm.
The KBX163 has an effective focal length (EFL) of 175 mm and a back focal length (BFL) of 172.8 mm. The radii of curvature for the first and second surfaces are 179.757 mm and -179.757 mm, respectively. The lens does not have any coating applied to its surfaces.
This uncoated lens is well-suited for applications that do not require an antireflective coating, such as imaging systems where the elimination of surface reflections is not a primary concern. The KBX163 is in stock and available through the MKS/Newport website, as indicated by its valid weblink status.
