LA2039 3 mm Dia. N-SF11 Plano-Convex Lens; EFL=9mm Uncoated

The LA2039 is a 3 mm diameter Plano-Convex spherical lens, sourced from the renowned optical components manufacturer, Thorlabs. This lens, crafted from the high-index N-SF11 glass by Schott, is designed to deliver exceptional optical performance, particularly for applications that require a longer effective focal length (EFL).

The lens features a convex surface with a 7.1 mm radius of curvature, while the opposing surface is planar. The center thickness of the lens measures 1.5 mm, with the edge thickness slightly thinner at 1.2 mm. This lens is uncoated, offering a cost-effective solution for applications where anti-reflective coatings are not required.

The LA2039 is optimized for a wavelength of 587.6 nm, making it suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications. The lens is available for purchase through the Thorlabs website, where it is currently in stock, ensuring quick delivery for your optical project needs.
