LA5370 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=40mm Uncoated

The LA5370 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from the reputable optical components manufacturer, Thorlabs. This lens is made from Calcium Fluoride (CaF2) material, specifically identified as "caf2 mal-1963" in the material database.

The lens geometry features a thickness of 2 mm at the edge and 7.5 mm at the center, with a 40 mm Effective Focal Length (EFL). The lens shape is spherical, with a radius of curvature (R1) of 17.4 mm for the curved face. The flat face has an inner radius of 0 mm and an outer radius of 0 mm, as expected for a plano-convex lens.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. The lack of coating may result in higher reflective losses and a lower transmission rate compared to coated lenses. However, uncoated lenses are often preferred in specific applications where the coating might introduce unwanted effects, such as spectral dispersion or polarization.

The lens is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by the "weblink status" field. With this information, users can make informed decisions regarding the suitability of this lens for their specific optical systems and applications.
