LA5025 12.7 mm Dia. CaF2 Plano-Convex Lens; EFL=25mm Uncoated

The LA5025 is a Plano-Convex lens with a diameter of 12.7 mm, sourced from the reputable optical components manufacturer, Thorlabs. This lens is made of Calcium Fluoride (CaF2) with a Mal-1963 material ID, which is a popular material for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.

The lens features an effective focal length (EFL) of 25 mm, making it suitable for a wide range of optical applications that require a moderate focal length. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The radius of curvature of the curved surface is 10.9 mm.

The LA5025 has a center thickness of 4.1 mm and an edge thickness of 2 mm, providing structural rigidity and minimizing potential distortions. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses often have lower reflectivity compared to coated ones, making them a good choice for applications where reflectivity needs to be minimized.
