KPX579 25.4 mm Dia. x 38.1 mm FL; Uncoated; Plano-Convex Lens
The KPX579 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 38.1 mm. This lens is sourced from the reputable vendor MKS/Newport, and its detailed specifications are available for reference on their official website. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by its diameter, thickness at the edge, and thickness at the center. The diameter is a consistent 25.4 mm, while the thickness at the edge is 3 mm and the thickness at the center is 7.64 mm. The effective focal length (EFL) is 38.1 mm, and the radius of curvature (R1) is 19.69 mm. The back focal length (BFL) is 33.06 mm, and the inner radius is 0 mm.
The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The lens is designed to operate at a wavelength of 546.1 nm. The shape of the lens is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
