LA5220 50.8 mm Dia. CaF2 Plano-Convex Lens; EFL=200mm Uncoated

The LA5220 is a Plano-Convex lens with a diameter of 50.8 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 deep UV range.

The lens geometry includes an outer radius of 0 mm, indicating a flat surface on one side, and an inner radius of 86.8 mm, which is the curvature of the convex surface. The lens has a thickness of 3 mm at the edge and 6.8 mm at the center. The Effective Focal Length (EFL) of this lens is 200 mm, making it suitable for use in imaging systems where a longer focal length is required.

The LA5220 is uncoated, meaning it does not have any anti-reflective coatings. This may result in higher reflective losses, especially at the air-to-lens interface, but it can be advantageous in applications where the user wants to avoid any potential alterations in the spectral properties of the material due to the coating.
