L-PCX047 6.4 mm Dia. Plano-Convex Lens; EFL=4.7mm Uncoated

The L-PCX047 is a Plano-Convex lens with a diameter of 6.4 mm, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in optical systems that require a convex lens with a flat surface on one side. The Plano-Convex design allows for a wide range of applications, including use as a focusing element or as a beam shaper in laser systems.

The lens has an effective focal length (EFL) of 4.7 mm, which is the distance from the lens's center to the point where the light rays converge. This makes it suitable for use in compact optical systems where space is at a premium. The lens's thickness at the edge is 1.2 mm, while the center thickness is 3 mm, providing a good balance between optical performance and mechanical robustness.

The lens is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and high transmission in the visible spectrum. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors. However, uncoated lenses can be more susceptible to surface contamination and may require more frequent cleaning.

The lens's geometry is spherical, with a radius of curvature of 2.42896 mm on the convex side. This curvature, combined with the lens's diameter and EFL, determines the lens's optical power and its ability to focus light. The lens's inner and outer radii are both 0, indicating that it is a simple, single-element lens.
