110-5240E 25.4 mm Dia. x 2000 mm FL; Uncoated; Plano-Convex Lens
The 110-5240E is a Plano-Convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens boasts a base shape of a circle and is designed for use with a wavelength of 2940 nm. The lens is uncoated, offering a cost-effective solution for applications where coating is not required.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm, which gradually increases to a center thickness of 3.1 mm. The effective focal length (EFL) of this lens is 2000 mm, making it suitable for applications that require long focal lengths. The lens's curvature is defined by a radius (R1) of 836.5 mm, with the inner and outer radii being 0 mm, indicating a plano surface on one side and a curved surface on the other.
This lens is made from CAF2 (MgF2) material, identified as "caf2 mal-1963" in the material database. The use of CAF2 offers excellent transmittance in the ultraviolet, visible, and near-infrared spectral regions, making this lens versatile across various applications.
