KPX199 50.8 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens
The KPX199 is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 200 mm. This lens is sourced from MKS/Newport, a renowned 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's geometry is characterized by a thickness of 3 mm at the edge and 6.17 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 of the curved surface is 103.36 mm, and the back focal length is 195.93 mm. The effective focal length (EFL) is 200 mm.
This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of optical elements, 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. It is spherical in shape, which is a common geometry for optical lenses due to its simplicity and effectiveness.
