KPX108 25.4 mm Dia. x 225 mm FL; Uncoated; Plano-Convex Lens
The KPX108 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 225 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 3.693 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 225 mm, and the back focal length (BFL) is 222.57 mm. The radius of curvature (R1) is 116.712 mm.
This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be suitable for applications where such enhancements are not necessary.
The lens is designed to work with a wavelength of 546.1 nm. It is spherical in shape, which is a common geometry for optical lenses due to its ease of manufacturing and good optical performance.
