KPX549 12.7 mm Dia. x 50.2 mm FL; Uncoated; Plano-Convex Lens

The KPX549 is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 50.2 mm, sourced from the reputable vendor MKS/Newport. This lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and versatility.

The lens's geometry is characterized by its plano-convex shape, where one side is flat (plano) and the other side is curved (convex). The thickness at the edge of the lens is 3 mm, while the center thickness is 3.78 mm. The lens's effective focal length (EFL) is 50.2 mm, and the radius of curvature (R1) is 25.94 mm. The back focal length (BFL) is 47.7 mm, and the inner radius is 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens in certain applications, uncoated lenses are often chosen for their cost-effectiveness and simplicity.

The KPX549 is designed for use at a wavelength of 546.1 nm. It is a spherical lens, which means it has a spherical surface—a common and versatile lens shape.
