L-PCX044 29 mm Dia. Plano-Convex Lens; EFL=160mm Uncoated

The L-PCX044 is a 29 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 element or as a beam shaper in laser systems.

The lens has an effective focal length (EFL) of 160mm, making it suitable for applications that require a longer focal length. The EFL is a critical parameter in lens selection, as it directly impacts the size and convergence of the image produced by the lens. A longer EFL, like that of the L-PCX044, results in a larger image and a narrower angle of convergence.

The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high transparency in the visible spectrum. The lens has a refractive index of 1.5168 at a wavelength of 587.6nm, which is within the visible light spectrum. This refractive index, combined with the lens's curvature, determines the lens's focusing power.

The lens's geometry includes a 2mm thickness at the edge and a 3.3mm thickness at the center. The inner and outer radii are both 0, indicating that the lens is a simple Plano-Convex design without any additional curvature or features. The lens's base shape is circular, providing symmetry and consistency in the optical path.

Notably, the lens is uncoated. While coatings can enhance the performance of a lens by reducing reflections, 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 often more resistant to damage from environmental factors.
