L-PCX195 25.4 mm Dia. Plano-Convex Lens; EFL=500mm Uncoated

The L-PCX195 is a Plano-Convex lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical elements. The Plano-Convex design features a flat surface on one side and a curved surface on the other, with the curvature determined by a radius of 258.4 mm.

The lens has an effective focal length (EFL) of 500mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This EFL makes the L-PCX195 particularly suitable for applications that require a long focal length, such as telescopes or high-powered microscopes.

The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. The lens's thickness at the edge is 3 mm, while the center thickness is 3.31 mm. The back focal length (BFL) of the lens is 496.66 mm, which is the distance from the rear surface of the lens to its focal point.

Notably, the lens is uncoated. While coatings can be applied to improve the lens's performance in specific applications, such as reducing reflection or increasing transmission, this lens is designed to provide optimal performance in its uncoated state.
