L-PCX152 18 mm Dia. Plano-Convex Lens; EFL=100mm Uncoated

The L-PCX152 is a Plano-Convex lens with a diameter of 18 mm, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in systems where a large diameter is not required, and a long focal length is needed. The Plano-Convex design, where one side is flat and the other is curved, is a common choice for applications that require a simple, single-element lens.

The lens has an effective focal length (EFL) of 100mm, which is the distance from the lens's center to the point where light rays converge. This makes it suitable for applications that require a long focal length, such as in telescopes or microscopes. The lens is made of N-BK7 Schott glass, a popular material for optical lenses due to its excellent optical properties and high Abbe number, which ensures low chromatic aberration.

The geometry of the lens includes a thickness of 1.5 mm at the edge and 2.3 mm at the center. The inner and outer radii are both 0, indicating a flat inner surface and a curved outer surface. The radius of curvature of the curved surface is 51.68 mm, and the back focal length (BFL) is 98.82 mm.

Notably, this lens is uncoated. While coatings can enhance the performance of a lens by reducing reflection and increasing transmission, an uncoated lens can be a cost-effective choice for applications where such enhancements are not necessary.
