111-1504E 50.8 mm Dia. x 50 mm FL; Uncoated; Double-Convex Lens
The 111-1504E is a spherical lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens falls under the category of a double-convex lens, featuring two convex surfaces. The lens has a diameter of 50.8 mm and a center thickness of 17.3 mm, with an edge thickness of 1.4 mm, providing a robust structure suitable for various applications.
The effective focal length (EFL) of this lens is 50 mm, which refers to the distance from the lens's center to the focal point when the lens is placed in an optical system. The first radius of curvature (R1) is 44.8 mm, and the second radius of curvature (R2) is -44.8 mm, indicating the curvature of the lens surfaces. The inner radius is 0 mm, and the outer radius is also 0 mm, suggesting that the lens has no peripheral flattening or steepening.
This lens is made of UVFS Mal-1965 material, specifically designed for use in the wavelength of 355 nm. The lens does not have any coating, which means it is uncoated, providing a clear, unaltered view of the light passing through it.
