LA5464 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=500mm Uncoated

The LA5464 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from the reputable optical components manufacturer, Thorlabs. This lens is made of Calcium Fluoride (CaF2) with a Mohs hardness of 3, making it an ideal choice for applications that require a material with excellent transparency in the ultraviolet, visible, and near-infrared regions.

The lens geometry includes an outer radius of 0 mm, indicating a flat surface, and an inner radius of 216.9 mm, which is the curvature of the convex surface. The edge thickness of the lens is 2 mm, while the center thickness is 2.4 mm. The Effective Focal Length (EFL) of this lens is 500 mm, making it suitable for use in imaging systems where a long focal length is required.

The LA5464 is uncoated, meaning it does not have any anti-reflective coatings. This may result in unwanted reflections, especially in high-power applications. However, it can be advantageous in applications where the user wants to control the phase or polarization of the light.
