The KPX124 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 1000 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The geometry of the lens includes a thickness of 3 mm at the edge and 3.156 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 (R1) is 516.8 mm, and the back focal length (BFL) is 997.91 mm. The effective focal length (EFL) is the same as the focal length, at 1000 mm. The wavelength for this lens is 589 nm.
This lens is suitable for applications that require a long focal length and a large diameter. Its uncoated nature makes it ideal for use in environments where coated lenses may not be necessary or practical. However, it is important to note that uncoated lenses can be more susceptible to damage from environmental factors, so they should be handled with care.
