KPX052 12.7 mm Dia. x 62.9 mm FL; Uncoated; Plano-Convex Lens

The KPX052 is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 62.9 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is made of N-BK7 Schott, a popular material for optical elements due to its excellent optical properties and wide transparency range.

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 3.626 mm. The lens's inner radius is 0 mm, indicating a sharply curved surface. The back focal length (BFL) is 60.5 mm, and the effective focal length (EFL) is the same as the specified focal length, at 62.9 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, uncoated lenses can be suitable for certain applications where such enhancements are not necessary.

The lens is designed to work with a wavelength of 589 nm, which is a common wavelength used in various optical applications. The lens's shape is spherical, which is the most common shape for optical lenses due to its ease of manufacturing and good optical performance.
