L-PCX231 15 mm Dia. Plano-Convex Lens; EFL=85mm Uncoated

The L-PCX231 is a Plano-Convex lens with a diameter of 15 mm, 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 surface on one side. The Plano-Convex design allows for a wide range of applications, including use as a focusing lens or a beam expander.

The lens has an effective focal length (EFL) of 85mm, making it suitable for use in medium to long focal length applications. The EFL is a critical parameter in lens selection, as it directly influences the field of view and the magnification of the optical system.

The lens is made from N-BK7 Schott glass, a popular material for optical lenses due to its excellent optical properties and high transmission in the visible spectrum. The lens has a center thickness of 3mm and an edge thickness of 2.4mm, providing robustness and durability.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While coatings can enhance the performance of a lens by reducing reflections and increasing transmission, uncoated lenses are often preferred in applications where cost and simplicity are paramount.

The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 43.928mm.
