KPX190 50.8 mm Dia. x 125 mm FL; Uncoated; Plano-Convex Lens
The KPX190 is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 125 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and wide transparency range. The lens's geometry is characterized by a thickness of 3 mm at the edge and 8.203 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other.
The radius of curvature (R1) is 64.6 mm, and the back focal length (BFL) is 119.59 mm. The effective focal length (EFL) is 125 mm. The wavelength for this lens is 589 nm.
This lens is ideal for applications that require a simple, uncoated lens with a long focal length. It can be used in various settings, including imaging systems, beam shaping, and other applications where a plano-convex lens is required. The uncoated version is suitable for use in air or other environments with similar refractive indices.
