45-429 4.0mm Dia. x 10.0mm FL; Uncoated; Plano-Convex Lens

The 45-429 is a 4.0mm diameter by 10.0mm focal length Plano-Convex lens, sourced from the renowned optical component vendor, Edmund Optics. This lens, made from the high-quality material n-BK7 Schott, is uncoated, offering a cost-effective solution for various optical applications.

The Plano-Convex lens features a base shape of a circle and a spherical geometry. The lens's edge thickness is 1.24mm, while the center thickness is 1.64mm, ensuring excellent light transmission and minimal distortion. The effective focal length (EFL) is 10mm, providing a concentrated light beam for various applications.

The lens's inner and outer radii are both 0mm, indicating a symmetrical curvature. The first radius of curvature (R1) is 5.19mm, contributing to the lens's focusing power. The back focal length (BFL) is 8.92mm, which is the distance from the lens's rear surface to the focus point.

This lens is designed to work with a wavelength of 587.6nm, making it suitable for applications such as imaging, beam shaping, and laser systems. With its uncoated surface, the lens provides high transmission across the visible spectrum, although it may exhibit higher reflectivity compared to coated lenses.
