KPX118 25.4 mm Dia. x 500 mm FL; Uncoated; Plano-Convex Lens

The KPX118 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 500 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.

The lens geometry is characterized by a thickness of 3 mm at the edge and 3.312 mm at the center. The inner radius is 0 mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 258.4 mm. The back focal length of the lens is 497.81 mm, and the effective focal length is 500 mm.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This may result in higher reflective losses and lower transmission compared to coated lenses. However, uncoated lenses are often more cost-effective and suitable for applications where such losses are acceptable or can be mitigated.

The lens is designed to operate at a wavelength of 589 nm. It is spherical in shape, which is a common and versatile geometry for optical lenses. The lens is circular in base shape, making it suitable for a wide range of applications.
