KPX208 50.8 mm Dia. x 400 mm FL; Uncoated; Plano-Convex Lens
The KPX208 is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 400 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.
The lens's geometry is characterized by a thickness of 3 mm at the edge and 4.566 mm at the center. The inner radius is 0 mm, and the lens has a base shape of a circle. The effective focal length (EFL) is 400 mm, and the back focal length (BFL) is 396.98 mm. The radius of curvature (R1) is 206.72 mm.
This lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide high-quality images, especially in applications where the light path is not subject to significant disturbances.
The lens is designed to work with a wavelength of 589 nm. It is a spherical lens, which is a common type of lens used in various optical systems due to its simplicity and effectiveness.
