L-PCX322 52 mm Dia. Plano-Convex Lens; EFL=100mm Uncoated

The L-PCX322 is a 52 mm diameter Plano-Convex lens, sourced from the renowned optical component vendor, Ross Optical. This lens is specifically designed for use in optical systems that require a convex lens with a flat plane on one side. The Plano-Convex design allows for a wide range of applications, including imaging, beam shaping, and light collimation.

The lens has an effective focal length (EFL) of 100mm, making it suitable for systems that require a longer focal length. The EFL is a critical parameter in lens selection, as it directly influences the size and convergence of the image formed by the lens. A longer EFL, like that of the L-PCX322, results in a larger image and a narrower field of view.

The lens is made from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and high transmission in the visible spectrum. The lens has a clear aperture of 52 mm, providing a large light-gathering area for improved light transmission.

The geometry of the lens includes a thickness of 2.9 mm at the edge and 9.9 mm at the center. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a flat surface on one side of the lens. The radius of curvature (R1) is 51.68 mm, and the back focal length (BFL) is 93.85 mm.

Notably, the lens is uncoated. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, and protecting the surface, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical properties are a priority.
