111-1226E 25.4 mm Dia. x 200 mm FL; Uncoated; Double-Convex Lens
The 111-1226E is a spherical lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens is a double-convex type, meaning it has two convex surfaces. The lens has a diameter of 25.4 mm and a thickness at the edge of 2.1 mm, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is 200 mm.
The lens's first radius of curvature (R1) is 189.9 mm, and the second radius of curvature (R2) is -189.9 mm, indicating a converging lens. The inner radius is 0 mm, and the outer radius is also 0 mm. This lens is made of UVFS MAL-1965 material, optimized for use with a wavelength of 355 nm.
The lens does not come with any coating, as indicated in the item data. This could make it suitable for applications where coating is not required or desirable. The lens's geometry and material make it suitable for use in various optical systems, including imaging systems, beam shaping, and other applications where a double-convex lens would be beneficial.
