KPX609 25.4 mm Dia. x 250 mm FL; Uncoated; Plano-Convex Lens
The KPX609 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 250 mm. This lens is sourced from MKS/Newport, a renowned 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 lens's geometry is characterized by a thickness of 3 mm at the edge and 3.62 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other.
The lens's effective focal length (EFL) is 250 mm, and the radius of curvature (R1) is 129.2 mm. The back focal length (BFL) is 247.61 mm. The wavelength for this lens is 546.1 nm.
This lens is ideal for applications that require a simple, high-quality lens with a long focal length. Its uncoated surface makes it suitable for use in environments where coated lenses may not be necessary or desirable.
