L-PCX515 15 mm Dia. Plano-Convex Lens; EFL=45mm Uncoated

The L-PCX515 is a 15 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 use as a focusing lens or a beam shaping element.

The lens has an effective focal length (EFL) of 45mm, making it suitable for use in systems where a longer focal length is required. The EFL is a critical parameter in lens selection, as it directly influences the lens's ability to focus light at a specific distance. A longer EFL, like that of the L-PCX515, provides a narrower field of view and a larger depth of field, making it ideal for applications where these characteristics are desirable.

The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high transmission in the visible spectrum. The lens's geometry includes a thickness of 1.9mm at the edge and 3.1mm at the center, providing structural integrity and resistance to deformation.

Notably, the lens is uncoated. While coatings can enhance a lens's performance by reducing surface reflections and increasing transmission, an uncoated lens can be advantageous in certain applications. For instance, uncoated lenses can be used in systems where surface reflections are not a concern, or where cost is a significant factor.
