L-PCX089 12 mm Dia. Plano-Convex Lens; EFL=84mm Uncoated

The L-PCX089 is a Plano-Convex lens with a diameter of 12 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 element or a beam shaper.

The lens has an effective focal length (EFL) of 84mm, 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 convergence or divergence of light passing through the lens. A longer EFL, as in the case of the L-PCX089, results in a narrower angle of convergence or divergence.

The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. This ensures high transmission across a wide range of wavelengths and low dispersion, making the lens suitable for use in broadband optical systems.

The geometry of the lens includes a thickness of 2.1mm at the edge and 2.5mm at the center. The inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other. The radius of curvature (R1) of the curved surface is 43.4112mm.

Notably, the lens is uncoated. While coatings can enhance the performance of lenses by reducing reflection, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications. For instance, uncoated lenses can be more cost-effective and are less susceptible to damage from environmental factors.
