L-PCX268 42 mm Dia. Plano-Convex Lens; EFL=250mm Uncoated

The L-PCX268 is a 42 mm diameter Plano-Convex lens, part of the extensive catalog offered by Ross Optical. This lens is designed with a spherical shape and a base shape of a circle, making it suitable for a wide range of optical applications.

The lens features an effective focal length (EFL) of 250mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity. This EFL makes the L-PCX268 a high-powered lens, ideal for applications that require a tight focus or magnification.

The geometry of the lens includes a thickness of 2mm at the edge and 3.7mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) is 129.2mm.

The L-PCX268 is made from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is widely used in various optical systems, including beam expanders, laser systems, and imaging systems.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in a higher level of light reflection, it also means the lens is more cost-effective and suitable for applications where such coatings are not necessary.
