KPX229 76.2 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens

The KPX229 is a Plano-Convex lens with a diameter of 76.2 mm and a focal length of 200 mm. This lens is sourced from the reputable vendor MKS/Newport, and its detailed specifications make it a versatile component for various optical applications.

The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. It is uncoated, which means it does not have any additional layers to enhance or alter its optical properties. This can be beneficial in applications where the natural properties of the material are desired, or where cost-effectiveness is a priority.

The geometry of the lens includes a thickness of 3 mm at the edge and 10.27 mm at the center. The inner radius is 0, indicating a flat surface on one side and a curved surface on the other. The radius of curvature (R1) is 103.36 mm, and the back focal length (BFL) is 193.22 mm. The effective focal length (EFL) is the same as the specified focal length, which is 200 mm.

This lens is designed for use at a wavelength of 589 nm. Its spherical shape and the specified wavelength make it suitable for a wide range of applications, from imaging and beam shaping to laser systems and interferometry.
