KPX091 25.4 mm Dia. x 88.3 mm FL; Uncoated; Plano-Convex Lens

The KPX091 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 88.3 mm. This lens is sourced from MKS/Newport, a reputable 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 geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 3 mm, while the center thickness is 4.803 mm. The lens's effective focal length (EFL) is 88.3 mm, and its radius of curvature (R1) is 45.633 mm. The back focal length (BFL) is 85.13 mm, and the inner radius is 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost is a significant factor. However, it's important to note that uncoated lenses can suffer from increased reflection, which may impact the performance in high-precision applications.

The lens is designed to operate at a wavelength of 589 nm. It is spherical in shape, a common geometry for optical lenses due to its relative ease of manufacturing and excellent optical performance.
