KPX543 12.7 mm Dia. x 25.4 mm FL; Uncoated; Plano-Convex Lens

The KPX543 is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 25.4 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 known for its excellent optical properties and wide transmission range.

The KPX543 features a convex shape on one side, with a radius of curvature of 13.12 mm, and is plano on the other side. The center thickness of the lens is 4.63 mm, while the edge thickness is 3 mm. The lens has a clear aperture of 12.7 mm, providing a wide field of view.

The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This can result in higher reflective losses, but it also means that the lens is more cost-effective and versatile, as it can be used in a wide range of applications without the need for specialized coatings.

The KPX543 is designed for use at a wavelength of 546.1 nm, making it suitable for applications in the visible spectrum. It is important to note that the performance of the lens can vary depending on the specific conditions of use, including the angle of incidence, the polarization of the light, and the spectral bandwidth.
