The 110-1225E is a Plano-Convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens has a base shape of a circle and is designed for use in the ultraviolet spectrum at a wavelength of 355 nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3.5 mm. The center thickness is slightly greater at 4 mm. The effective focal length (EFL) of the lens is 350 mm, which is the distance from the lens's center to the focal point. The radius of curvature (R1) of the curved surface is 166.6 mm. The lens does not have an inner radius (R2), and the outer radius (R3) is also not specified, indicating that the lens is finished to the edge of the material.
The lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet spectrum. This material is in stock and available for immediate purchase, as indicated by the "weblink status" field. The lens is part of EKSMA Optics' UV-FS Plano-Convex Lenses category, and more information about this product can be found on their website.
