LA1289-AB 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=30mm 400-1100nm

The LA1289-AB is a 12.7 mm diameter Plano-Convex lens made from N-BK7 glass, a popular material in optical systems due to its excellent optical properties. This lens boasts an effective focal length (EFL) of 30mm, making it suitable for a wide range of applications. The lens is designed to work within the wavelength range of 400-1100nm, covering a significant portion of the visible light spectrum and extending into the near-infrared region.

The lens features a front and back coating of THo AB Bbar, a broadband anti-reflection coating that reduces surface reflections and increases transmission. This coating is particularly beneficial when dealing with broadband light sources or when high transmission is required.

The geometry of the lens includes a thickness of 1.8mm at the edge and 3.2mm at the center, providing a robust structure while maintaining a low profile. The lens's shape is spherical, with a radius of curvature of 15.5mm on the curved side. The flat side, or the planar side, has an inner radius of 0mm and an outer radius of 0mm, making it ideal for applications that require a flat surface.
